-This game is illogical! If it feels like you're going in circles, think sideways.
-The walls with eyes vanish if you stare at them.
-The red gun allows you to create infinite cubes, provided you have two of them.
-Orange forcefields erase blocks in the gun, not inside of the field.
-Purple forcefields erase any blocks in or out of the gun.
-If you're stuck, go back to the beginning and try a different way.
-The timer is inconsequential.

• This is very straightforward, as transparent as glass.
  
• Holding doors open may be a way to satisfy others.
  
• Returning can change things wholly.
  
• When nothing seems to work, find another way.
  
• Pits are made for falling into most of the time.

Still not sure? Try peering deeper into the darkness.

• Not all puzzles can be completed without the right equipment.
  
• Paths through the labyrinth are no longer so straight.
  
• Consider all colours of cube yours to take, but not always yours to use.
  
• Puzzles are still straightforward, if you can get your head round your new ability.
  
• Attempt to keep your cubes, as they are vital.

Still don't get it? Not all the puzzles you meet are solvable first go. Try a different approach, and then admit defeat. Sometimes the map is roundabout, but keep in mind that it isn't yet possible to go everywhere.

• Growing up means new abilities, and ways to replicate what you have.
  
• Old impossibilites can be overcome with experience.
  
• Build bridges for burning.
  
• Keep your eyes open for things reflecting your new colour.

Unsure? This is pretty much the most difficult phase of the game, so don't give up. Connecting points can let you break more than one at once.

• Your powers are now fully-fledged, but there is room to grow up yet.
  
• Revisit your past, and find the little things you can fix now.
  
• Power is nothing without wisdom.
  
• Answers are easier when you know what you need to do,
  
• Not all obstacles are truly there.

Stuck? Your new "pull" ability can move things around for you! This lets you make lifts, bridges and knock down what is in your way!

• The end of life brings the greatest challenges of all.
  
• Leaving behind your past is a fatal mistake.
  
• Above all else, remember how close the end has been before.
  
• Seeking out finality brings it faster.
  
• Drawing in what you find around you will solve all life's mysteries.

Helpless? Find where the "ghostly cube" has gone.

MAJOR SPOILER: THE END

• Finally, the end.
  
• Giving up is not an option now.
  
• Find something akin to what you seek in the night sky.
  
• Yield your knowlege, else nobody will ever become wise.

No way forward? Jump.

• Dead ends hide the valuable secrets.
  
• There are no further paths beside what you have already found.

Stuck? There is no being stuck anymore. Try harder.
