The Road to Gehenna DLC is out and some of those pesky Stars are really hard to get! If you need a hint or straight up want to know how to get them, this is the place to be.

If you are looking for hints in finding the stars in the base game, check out my other guide:
http://steamproxy.net/sharedfiles/filedetails/?id=354991567


Each section covers a single level. In each section has two parts:

• How to find the star
  
• How to actually get the star

For each part I tried to list hints, starting from vague directions and leading to the actual solution. So if the first hint doesn't help, you can check the next one, and so on.

NOTE: Most stars are located in plain-sight so I didn't really have any hints to offer on how to locate the stars. Of course, getting them is always tricky, so there should be plenty of hints there.

There are a total of 16 stars. However, you only need 10 stars to open the gate to the extra 'secret' puzzles.


Notice those small floating islands in the hub level? One of them has the entrance to the 'secret' puzzle level with really tough puzzles! To open the entrance you will need 10 stars.

To actually reach that small floating island, you have to take a series of Fan-jumps... The starting point is located on the 4th island (the island with the entrance to Zone 4) behind the big fancy building in the middle of the floating island. Just look around the edge and you should see a small floating island with a fan on it. Jump down and begin the wild ride! At some point you will land on a Fanless island and will have to jump down to another island that does have a fan. Other than that, it's straightforward.
Good luck finding the Stars, hopefully you won't have to use this guide too much.

NOTE: Since the guide was just published, some hints may be incorrect or too vague. Please let me know in the comments if a section is problematic.

Where is it?

• 1st hint: On top of a wall, should be easy to spot...
  
• Solution: On top of the wall behind the first Blue Forcefield Barrier.

How to get it?

• 1st hint: You need to find a way to climb the wall...
  
• 2nd hint: Try looking for things that are next to the wall and that can be climbed.
  
• 3rd hint: Gargoyle Statues. Find them. Climb them.
  
• 4th hint: The Gargoyle statues in the area beyond the third Blue Forcefield can be climbed using the Hexahaedron.
  
• 5th hint: Once you're on the wall, just keep heading towards the Star. Use the Hexahaedron to climb on the higher parts of the walls and the rest of the path should just be auto-jumps.
  
  
• Solution: Use the Connector to link the first Blue Receiver and all of the fixed Connectors above. Place the fan on the button to open the second Blue Forcefield. Take the Hexahaedron with you in the area after the third Blue Forcefield. Use it to climb the Gargoyle and take it with you. Continue along the wall towards the Star using the Hexahaedron along the way when you need to climb a higher part of the wall. The path should be marked by lots of auto-jump spots.

Where is it?

• 1st hint: On top of a wall and it's pretty hard to see... Around the middle of the puzzle area.
  
• Solution: On top of the gate/wall opposite to the Messenger you're supposed to free.

How to get it?

• 1st hint: You can't just climb the wall, you need to find a certain Fan...
  
• 2nd hint: Try looking for the Fan you need in the rear area of the puzzle...
  
• 3rd hint: The Fan is behind the So Close, So Far puzzle area, enclosed by some walls. You can get to it by jumping over a rock at a gap in the wall.
  
• 4th hint: To activate the fan, proceed similarly to solving the puzzle, but this time link the Red Laser last.
  
  
• Solution: Look behind the So Close, So Far puzzle area behind a walled off area for a Fan. You can get through the walls by jumping over a rock at a gap in the wall... Go place the Hexahedron onto the Red Fan platform you used to solve the puzzle. Place the Connector linked to both Fan Blue Laser Receivers. Finally, activate the Red Fan using the second Connector - simply go way way in front of the Red Laser Source until you see both the Source and the Receiver.

Where is it?

• 1st hint: On top of a wall enclosing the spawn area.
  
• Solution: On top of the gate to the Through a Window puzzle area.

How to get it?

• 1st hint: You'll need to smuggle a Hexahaedron into the Spawn area from one of the puzzles...
  
• 2nd hint: The easiest place to get a Hexahaedron is the Open Field puzzle.
  
• 3rd hint: You can get the Hexahedron over the wall at the Puzzle Entrance, by using the Hexahaedront o climb the walls here.
  
• 4th hint: In the Open Field puzzle, climb the walls with the small windows next to the Puzzle Entrance, from top of them you can do an auto-jump over the big wall.
  
• 5th hint: Look for a spot to climb in the corner left of the Through a Window puzzle entrance.
  
• 6th hint: After you climb the wall, use the Hexahaedron to climb onto a narrow ledge on the side of a square tower.
  
  
• Solution: Go to Open Field and get the Hexahaedron to the puzzle entrance. Use it to climb the walls with the small windows next to the entrance. (Place the Hexahaedron on top of the stairs, jump on the higher platform and grab the Hexahaedron. Place it next to the thin wall, climb it, then grab the Hexahaedron again.) From here you can do an auto-jump on top of the BIG WALL.
  
  After you get over the Big Wall with the Hexahaedron, go in the corner to the left of the entrance to Through a Window. Use the blocks next to the wall here in combination with the Hexahaedron to climb the wall. Don't forget to take the Hexahaedron with you up on the wall.
  
  Once on the wall, place the Hexahaedron next to the square Tower that is closest to the Through a Window puzzle. From the Hexahaedron, jump onto the ledge at the side of the tower and then take the Hexahaedron with you again. From the other end of the ledge, you can auto-jump onto one of the arches in front of you.
  
  Finally, just walk towards the Star and use the Hexahaedron one last time to jump over to it.

Where is it?

• Solution: You can see it from the Messenger's prizon in this puzzle... No mystery here.

How to get it?
Note #1 I'll be referring to the side with the Red Laser Source as the RIGHT side and the side with the Blue Laser Source as the LEFT side.

Note #2 There are many ways to solve this puzzle, some more convoluted than others. This should be one of the simpler ways to do it...

• 1st hint: Start by getting both Connectors to the RIGHT side.
  
• 2nd hint: At the start of the recording, you'll have to get the Real Connectors back to the LEFT side and at the same time use the Recorded Connectors to get the Red Laser through the window at the back of the puzzle area from the RIGHT side to the LEFT side.
  
• 3rd hint: While the recording is active, you need to link all of the Blue Laser Receivers at the same time.
  
• 4th hint: While the recording is active, you need to open both LEFT and RIGHT side final Forcefields by placing Fans on their Buttons.
  
  
• Solution: Get both Connectors to the RIGHT side. Place Connector #1 in the corner with the Blue Receiver. Place the Fan onto the Forcefield Button. Place Connector #2 linked to Connector #1, the Red Laser Source, AND so that it sees through the mid-section Wide Windows.
  
  Start a recording. Your goal here is to allow yourself to grab both Connectors and the Fan back to the LEFT side. After that just stand on the Forcefield Button for a while.
  
  EX: [RECORDING] Stand on Forcefield button for 10 seconds. Stand on Fan Button for 25 seconds. Stand on Forcefield Button for 30-40 seconds. [END RECORDING]
  
  While the Recording is active, get both Connectors and the Fan back to the LEFT side. Start with Connector #2, jump into the fan, place Connector #2 on the Left Side Fan button. Go back to the Right side and get the rest of the items.
  
  When you get everything on the LEFT side: Place Connector #1 on the Blue Laser Source Button while linking to the Red Receiver and to the RECORDED Connector #1 through the window. Place Connector #2 so it links to all of the Blue Receivers and the Blue Source at the same time. (The Star's Receiver will be blocked by the forcefield for now.) Place Connector #1 so it links the mid-section Forcefield Red Receiver to the RECORDED Connector #2 through the mid-section Wide Windows.
  
  Finally, place the two Fans on the buttons that open the forcefields leading into the final area before the Star. Grab Connector #1 and use it to link the Red Laser Source and the Star's Red Laser Receiver.

How to get it? - Alternate solution by Allah
Note #1: I'll be referring to the side with the Red Laser Source as the RIGHT side and the side with the Blue Laser Source as the LEFT side.

Note #2: Despite the long solution spoiler area, this solution is A LOT easier than my initial solution.

• 1st hint: You can smuggle the two Connectors and a Hexahaedron from Open Field into So Close, So Far.
  
• 2nd hint: Look around just behind the So Close, So Far puzzle...
  
• 3rd hint: Just behind the So Close, So Far puzzle, there are some stone-blocks that form some sort of stairs (Close to the RIGHT side of the So Close, So Far puzzle.) You can jump on those stairs from a nearby rock and take the Connectors and Hexahaedron with you.
  
• Solution:
  Go into Open Field just behind So Close, So Far. Close to the RIGHT side, next to the wall, there should be a stair-like structure. You can climb on those stairs by jumping from a nearby rock. From the stairs you can jump over the wall into So Close, So Far.
  
  Smuggle the two Connectors and Hexahaedron from Open Field into So Close, So Far.
  
  Get 2 Connectors in the RIGHT side and 2 Connectors in the LEFT side. Keep the Hexahaedron in the RIGHT side.
  
  In the RIGHT side:
  Place the Hexahaedron onto the button that opens the Barrier.
  Place Connector #1 so it links to the Red Source, it sees through the two Wide Windows in the middle of the puzzle, and it sees in the direction the Blue Receiver in the first room in this side.
  Place Connector #2 in the corner with the Blue Receiver, linked to Connector #1.
  Start a recording and activate the fan so you can go back to the RIGHT side once the recording is over...
  
  In the LEFT side:
  Place Connector #3 on the button controlling the forcefield and also link it to the Red Receiver.
  Place Connector #4 so it links the Blue Laser Source to all three of the Blue Receivers.
  Place Connector #3 so it links the Red Receiver that opens the last barrier, to the Red Connector from the RIGHT side, through the windows.
  
  Finally:
  Get the Fan from its socket and place it on the button to open the last Barrier on the RIGHT side.
  Get Connector #2 and use it to activate the Star's Red Receiver.
  Grab the Star!

Where is it?

• Solution: Just after hitting the puzzle switch, you'll see a Fan with a Blue Receiver. The Star is above the fan.

How to get it?

• 1st hint: You'll need to activate the Blue Receiver from above.
  
• 2nd hint: Notice all the fallen pillars? Maybe you can use them to climb around.
  
• 3rd hint: You can place the Hexahaedron on top of a Column to jump further.
  
• 4th hint: You only need the Hexahaedron and a Connector to solve this...
  
• Solution: First, get the Hexahaedron and a Connector into the area with the Blue barriers. Next, grab the Hexahaedron and head for the fallen column that is in the corner to the right of the Purple Forcefield. Climb up the wall that should be to your right, then jump onto the column that lies fallen on a long stone beam.
  
  You can place the Hexahaedron on top of a column at the end of the long stone beam. You can now use it to jump to the other undamaged stone beam. Take a Connector with you before you jump.
  
  After jumping onto the undamaged stone beam, place the Conector at the very end, linking the Blue Laser Source behind the Blue Forcefield to the Blue Fan Receiver. Finally, just jump into the Fan to collect your reward!

Where is it?

• Solution: You should plainly see it after you solve Static Vexer, right before climbing the stairs out of the final puzzle room.

How to get it?

• 1st hint: Cube Driver seems to be the only puzzle where you can get a Red Laser from into Static Vexer.
  
• 2nd hint: You don't need to keep the Red Receiver active at all times. Once you trigger it, the gate remains open.
  
• 3rd hint: After you open the gate, simply solve the puzzle one more time, taking the Jammers with you all the way.
  
• Solution: If you haven't solved it once already, solve Static Vexer then reset the puzzle. Now go to Cube Driver and place a Connectors so it stares towards the Static Vexer entrance through the leftmost wide wall window. Go back to Static Vexer and link the Star Receiver to the red Connector in Cube Driver
  
  After you trigger the Star gate Receiver once, simply solve the puzzle, but make sure to bring the two Jammers with you all the way to the end of the puzzle. Use them to Jam the two mines and collect the Star.

Note: There are probably multiple ways to get this one, I'll probably add more solutions later on.
Note: I'll refer to the side with the Blue Laser Source as the BLUE SIDE and the side with the Red Laser Source as the RED SIDE. The main area of the puzzle that is neither enclosed in the BLUE SIDE nor the RED SIDE shall be referred to as OUTSIDE.

Where is it?

• Solution: On the BLUE SIDE, behind a Forcefield.

How to get it? - Solution inspired by Dunvi's and Solais' suggestions regarding the Crater Stars.

• 1st hint: Try getting 1 Connector OUTSIDE, at least 3 Connectors in the BLUE SIDE and at least 1 Connector in the RED SIDE.
  
• 2nd hint: Start by taking the central floating Connector into the OUTSIDE area. (Simply drop it during your flight after you grab it.)
  
• 3rd hint: By placing the OUTSIDE Connector in the right spot, you should be able to send the Blue and Red beams over eachother.
  
• 4th hint: Place the OUTSIDE Connector on the elevated platform where the Jammer was initially.
  
• 5th hint: You can use the Jammer to open one of the two barriers in the middle of the BLUE SIDE.
  
• Solution: First, solve the puzzle normally. You should now have 4 Connectors in the RED SIDE, 1 Floating, and 1 in the BLUE SIDE.
  
  Jump into the RED SIDE Fan, grab the floating Connector, and drop it outside. After you land, get yourself OUTSIDE and place the Connector you just dropped on top of the slightly elevated platform where the Jammer was initially. Make sure to also link it to the Red Receiver in the BLUE SIDE that controls the Forcefield.
  
  You should be able to use 1 Connector in the BLUE SIDE and 2 more in the RED SIDE to reactivate the angled Fan over in the RED SIDE. This frees up the other 2 Conectors in the RED SIDE so you can take them with you to the BLUE SIDE.
  
  You should now have 1 Conector OUTSIDE, 3 Connectors in the BLUE SIDE and 2 Connectors in the RED SIDE.
  
  Use a Connector from the RED SIDE to connect to the OUTSIDE Connector.
  
  Use the Jammer to unlock the second Forcefield in the BLUE SIDE.
  
  Use one Connector in the BLUE SIDE to send the Red Beam from the connector OUTSIDE to the Star's Red Receiver. Use two Connectors to link the Blue Laser Source to the Star's Blue Receiver.
  
  NOTE: A good place to put the Red Connector and the second Blue Connector is near the right side of the first Forcefield you opened, with the Blue Connector being closer to the cliff-side.

How to get it? - Quaestio's cheeky solution

• 1st hint: The Jammer can jam some barriers over the metal fences...
  
• Solution: You can use the Jammer to jam the Barriers that hide the Fans and the first Star from the OUTSIDE area.
  
  In the OUTSIDE area, get the Jammer and go towards the metal fence of the room with the first Star. Stand next to the big obelisk so you can see the Star's Barrier and keep jumping up and down. At the peak of your jump, you should be selecting the Barrier.
  
  If you let go of the Jammer at the peak of the jump just as it selects the Barrier, you will successfully jam the Barrier from outside the room.

How to get it? - My initial solution

• 1st hint: One way to do it is to get 4 Connectors in to the BLUE SIDE.
  
• 2nd hint: Start by taking the central floating Connector over to the Blue side.
  
• 3rd hint: Use the Jammer to jam the second Forcefield in the BLUE SIDE - the one with a single Blue Laser Receiver.
  
• 4th hint: Use the remaining Connector in the RED SIDE to send a Red laser to the BLUE SIDE.
  
• Solution: First, solve the puzzle normally. You should now have 4 Connectors on the RED SIDE, one Floating, and one on the BLUE SIDE.
  
  Jump into the RED SIDE angled Fan, grab the floating Connector and take it with you to the BLUE SIDE.
  
  You should be able to use 1 Connector in the BLUE SIDE and 2 more in the RED SIDE to re-activate the angled Fan over in the RED SIDE. This frees up the other 2 Conectors in the RED SIDE so you can take them with you to the BLUE SIDE.
  
  You should now have 4 Connectors in the BLUE SIDE and 2 Connectors in the RED SIDE.
  
  Use one Connector from the RED SIDE to send a Red Laser towards the BLUE SIDE.
  
  Use a CONNECTOR to open first Forcefield by linking its Red Receiver to the laser from the RED SIDE.
  
  Use the Jammer to open the second Forcefield.
  
  By placing two Connectors near the right side of the first Forcefield you just opened, you should be able to easily link the Star's Red and Blue Receivers to their corresponding Lasers.

Note: Like with the previous Star, there are probably multiple ways to get this one, I'll probably add more solutions later on.
Note: I'll refer to the side with the Blue Laser Source as the BLUE SIDE and the side with the Red Laser Source as the RED SIDE. The main area of the puzzle that is neither enclosed in the BLUE SIDE nor the RED SIDE shall be referred to as OUTSIDE.
Note: This is probably the hardest Star to get in the whole DLC.

Where is it?

• Solution: In the middle of the Crater puzzle.

How to get it? - Solution inspired by Dunvi's and Solais' suggestions regarding the "Crater" Stars.

• 1st hint: Before you can collect this Star, you'll need to have solved the previous Star puzzle.
  
• 2nd hint: The only way to reach the Star is from above. You need to find a way to drop down to it...
  
• 3rd hint: All of the tools you need are in this puzzle.
  
• 4th hint: A mid air collision could drop you down to the Star.
  
• 5th hint: If you could launch the Hexahaedron from one Fan and yourself from the other at the same time, you would collide with it above the Star and fall down to it...
  
• 6th hint: With the right Connector placement, you can keep the Hexahaedron perpetually floating from one fan to the other. Then it's simply a matter of timing your jump into one of the Fans so you hit it.
  
• 7th hint: By placing a connector OUTSIDE in the right location, you can 'cross' the beams by sending one above the other.
  
• 8th hint: Place the connector OUTSIDE on top of the platform where the Jammer was initially.
  
• Solution: Solve the previous Star's puzzle using the solution which leads to having: 1 connector OUTSIDE, 3 Connectors in the BLUE SIDE and 2 Connectors inthe RED SIDE.
  
  Place the second fan in its socket in the BLUE SIDE and activate it. Activate the floating Hexahaedron and the fan you just placed. Next, jump into the angled fan, grab the floating Hexahaedron and place it on the Fan over in the RED SIDE.
  
  Go to the BLUE SIDE and take one connector back to the RED SIDE.
  
  You should now have 1 Connector OUTSIDE, 2 Connectors in the BLUE SIDE, 3 Connectors in the RED SIDE.
  
  You should be able to easily link the angled Fans in the BLUE and RED SIDES at the same time now.
  
  Afterwards, it's just a matter of jumping into one of the angled Fans and colliding with the Hexahaedron that is flying between the two Fans. You should be dropped down on top of the central stone structure - from here you can jump down over the fence to where the Star is. (Actually, if you time your collision right you'll land exactly on the Star!)
  
  For the BLUE SIDE FAN: Use 1 Connector from the RED SIDE, 1 Connector OUTSIDE, 1 Connector from the BLUE SIDE.
  
  For the RED SIDE FAN: Use 1 Connector from the BLUE SIDE and 2 Connectors from the RED SIDE.

How to get it? - My initial convoluted solution

• 1st hint: Before you can collect this Star, you'll need to have solved the previous Star puzzle.
  
• 2nd hint: The only way to reach the Star is from above. You need to find a way to drop down to it...
  
• 3rd hint: All of the tools you need are in this puzzle.
  
• 4th hint: A mid air collision could drop you down to the Star.
  
• 5th hint: If you could launch the Hexahaedron from one Fan and yourself from the other at the same time, you would collide with it above the Star and fall down to it...
  
• 6th hint: With the right Connector placement, you can keep the Hexahaedron perpetually floating from one fan to the other. Then it's simply a matter of timing your jump into one of the Fans so you collide with it.
  
• 7th hint: You can link one Fan Receiver directly, while using a Connector placed on the Hexahaedron itself to link to the other...
  
• 8th hint: Try linking the Blue Fan Receiver using a Connector placed on the Hexahaedron and two aditional Connectors (One in the BLUE SIDE, one in the RED SIDE). The Rad Fan Receiver can be linked directly using one connector in the RED SIDE and two in the BLUE SIDE.
  
• Solution: Solve the previous Star's puzzle using the solution which leads to having: 4 Connectors in the BLUE SIDE and 2 Connectors inthe RED SIDE. You should also have the Hexahaedron still stuck in its cage above the central Fan and the two angled Fans mounted in their sockets.
  
  Send the Red Laser towards the BLUE SIDE using one of the Connectors. In the BLUE SIDE, use the Connectors to activate both the central Fan and the angled Fan. Jump in the angled Fan and take the floating Hexahaedron with you over to the RED SIDE. Now link the angled Fan in the RED SIDE instead of the other one. Use it to take the Hexahaedron over to the BLUE SIDE.
  
  You should now have 4 Connectors in the BLUE SIDE, a Hexahaedron in the BLUE SIDE, and 2 Connectors in the RED SIDE.
  
  In the RED SIDE: Place a Connector in the room with the angled Fan, near the Barrier closest to the Red Laser Source so that it is visible through the fence from the BLUE SIDE. Link it only to the Fan's blue Receiver. Place the other Connector so it sends the Red Laser towards the BLUE SIDE.
  
  In the BLUE SIDE: Link a Connector through the purple Forcefield to the Blue Forcefield's Red Receiver. Place the Hexahaedron on top of the angled Fan. Place a connector linked to the Blue Source, just left of the purple Forcefield. Place the third connector on top of the Hexahaedron, linked to the previous connector and to the Connector in the RED SIDE that is linked to the Blue Receiver (you can select it through the fence). Use the fourth and final Connector to link the previous Red Connector to the Fan's red Receiver.
  
  If you've done everything right, the Red Fan should be active all of the time and the Blue Fan should activate at the last second as the Hexahaedron is floating towards it. If it's not working properly, try adjusting the position of the Connector linked to the Blue Laser Source and the Connector linked to the Blue Receiver over on the RED SIDE.
  
  Now you just have to jump into one of the angled Fans so you collide with the Hexahaedron in mid air. Even if you don't fall on top of the star and you land on top of the stone structure in the middle, you can jump down at the Star.

Where is it?

• 1st hint: Near where one of the Red Laser Sources is...
  
• Solution: In the courtyard beyond the big Purple Barrier, left of the Blue Barrier that blocks the Red Laser.

How to get it?

• 1st hint: Jam a barrier through a square wall window.
  
• 2nd hint: Try getting a Hexahaedron over into the courtyard beyond the Purple Barrier...
  
• 3rd hint: After acquiring the Fan Blades, you can solve the puzzle and activate the fan using just one of the two Hexahaedrons...
  
• Solution: First, solve the puzzle. Note that you can place the Connector on the second button directly and still connect it to both Laser Sources...
  
  This should free the second Hexahaedron, so pick it up, and take it with you into the fan and up at the Switch's platform. From here you can jump on top of the wall leading to the courtyard with the Red Laser Source behind a Blue Forcefield. Now you should have a Hexahaedron and a Connector in this yard.
  
  Next, simply jam the first Blue Forcefield through the window next to the second button. Go over the wall using the ladder and use the Connector and Hexahaedron to open the second and third barriers that block your way to the Star.

Where is it?

• Solution: Right next to the puzzle's final Switch...

How to get it?

• 1st hint: To activate the second Blue Laser Receiver, you will have to solve the puzzle without 'pendulating' the laser beam...
  
• 2nd hint: If only you could place the Connector somewhere higher so the beam can go through the windows without having to sit on a moving Shocker...
  
• 3rd hint: Climbing walls and nearby hills is required...
  
• 4th hint: Some creative Hexahaedron placement is also required to assist the wall climbing...
  
• Solution: First, grab the two Hexahaderons and take them to the entrance furthest from the Bridge. While facing the entrance, stack the two Hexahaedrons on top of eachother in such a way that their corner touches the right side corner of the brick gate structure. Now, go get a Connector and place it next to the Hexahaedrons.
  
  Go on the nearby hill left of that entrance, and drop down on top of the wall left of the entrance. From this wall, you should be able to jump on top of the two stacked Hexahaedrons. Pick up the connector and place it on the wide wall right of the entrance. Pick up the top Hexahaedron and follow the wall until the edge next to where there's an arching alcove on your left. Place the Hexahaedron here and get the Connector. From the Hexahaedron, jump with the Connector on to the taller wall at the other side of the arched alcove.
  
  Simply follow the platform you are on until you can see the Blue Laser Source. Place the connector so that it links the Source and it looks through the left most top window in the tall wall in the middle of the puzzle area.
  
  Now go back down, grab the Hexahaedron from the gate, and place it on top of the elevated platform nearest to the prison cell. You should be able to place the second Connector on top of it so that it links to the first Connector and both of the Blue Laser Receivers. Use the Jammer to disable the middle barrier and you can now get the Star!

How to get it? - Alternate solution, credits to b0mb and Dabus

• 1st hint: You can take the Connectors from the BFF puzzle...
  
• 2nd hint: In the BFF Puzzle, you can place a Hexahaedron on the button farthest from the entrance. From the Hexahaedron, you can climb over the walls...
  
• 3rd hint: Once on top of the Hexahaedron, facing opposite from the entrance, look at the left corner. You should be able to perform an auto-jump there.
  
• Solution:
  In the BFF puzzle, you can place a Hexahaedron on the button farthest from the entrance. Jump on top of the Hexahaedron, facing opposite from the entrance, look at the left corner. You should be able to perform an auto-jump there. (It may be a bit tricky, but it should work.)
  
  Now you can just take a Connector from the BFF puzzle to the hill near the Pendulum puzzle and use it to send the blue laser around the central wall in Pendulum.

Where is it?

• 1st hint: The walls around Pendulum enclose a larger area than the area the puzzle takes place in...
  
• 2nd hint: From the bridge, looking down at Pendulum, you should see a rather large and suspicious courtyard adjacent to the puzzle area itself... If you look from the right angle, you should even see the Star.
  
• Solution: Entering Pendulum from the side with the bridge, just right of the entrance is a wall behind which is hidden a secret courtyard. In that courtyard there is a Star hidden behind more walls... If you stand on the bridge in front of the puzzle's entrance, look to the right, behind the wall that is next to the Messenger's prison cell. You should see the Star there...

How to get it?

• 1st hint: There are three Shockers in Pendulum, one of which moves differently from the rest and isn't used in the standard puzzle solution...
  
• 2nd hint: You can stack two Hexahaedrons on the third Shocker and use them to jump over a certain wall leading to the Star...
  
• Solution: Notice the Shocker that patrols perpendicularly to the other two... Your goal is to stack two Hexahaedrons on it, and from them, jump over a wall near the Puzzle's prison cell.
  
  First stack a single Hexahaedron on top of the Shocker. While holding the second Hexahaedron, climb the first from the platform next to the Shocker's patrol route. Get off at the end opposite to the prison cell, on to the elevated brick platform next to the wall there. When the Shocker returns to that spot, carefully place the second Hexahaedron on top of it.
  
  Next, you should be able to jump on top of the Hexahaedrons. Simply ride to the other end of the patrol route and jump on top of the wall to your left.
  
  Now, drop down on to the lower and wider brick wall behind the wall on which you are standing. Walk along sticking close to the right side wall, and you should reach the Star after turning right two times.

Where is it?

• 1st hint: It is floating above the river...
  
• 2nd hint: ...between Pendulum and Ray Trivia
  
• Solution: It is floating above the river, between Pendulum and Ray Trivia. Not much else to say...

How to get it?

• 1st hint: There is a fan somewhere up high that can throw you at the Star...
  
• 2nd hint: Try looking at the highest level of the bridge for the Fan. Some platforming is required.
  
• 3rd hint: The easiest way to activate the Fan is to get a Red Laser Beam over from Ray Trivia.
  
• 4th hint: If you're having trouble aligning the beam, try using the bridge Connector to link the Fan's receiver to the Red Receiver from Ray Trivia that opens the prison cell gate. That should give you an idea of where the beam should go through...
  
• Solution: There is a Fan in the middle of the highest level of the bridge/aqueduct. Climb over to it and you'll see a Fan with a Red Laser Receiver, a Connector, and a bunch of Purple Barriers... Use the Connector to link the Fan's Laser Receiver to the Red Laser Receiver from Ray Trivia that opens the prison cell gate. By linking to the Red Receiver in Red Trivia like this, you'll have an easier time aligning the Connector in Ray Trivia correctly.
  
  Now go down to Ray Trivia and use the three connectors to link to the bridge Connector.
  
  Go back to the top of the bridge and jump into the Fan's stream to collect the Star.
