very tricky map . thumbs up!

Thanks for your reply. You're welcome :) .

Thanks, that certainly helped. Your method is a lot harder than the intended solution. It took multiple attempts to get it right, even when you knew what you wanted to do. I've removed some white walls to make your solution less obvious and hopefully more difficult to complete; although I don't think I can remove it completely without redesigning the entire room. I've also added a simple fix for reaching the companion cube too early.
The lasers in the pit are just an extra layer of danger for players who fall in.
The rest of the chamber was executed perfectly, thanks for playing and for your help.

OK, so I recorded my playthrough. You can download it {ĐƯỜNG DẪN BỊ XÓA}here. Sorry for the failing at the end. Hope it will help :) .

PS: One last question, for what purpose are the lasers in that pit (in front of the buttons to the exit)?

Your solution to reaching the ceiling button was correct but I can't seem to work out how you solved it beyond that. Using the blue gel for any jump in that room should overshoot the opening to the exit door area because that's not the intended use for the blue gel. Also, I have no idea how you managed to reach the companion cube at the end from underneath, it should be unreachable thanks to the glass panels/lasers.
Would you mind explaining how you solved it in a bit more detail? A video of your solution would really help if you know how to create one. It's been a while but I think there's a built in recording system you can activate using console commands that creates the video for you.

Nice chamber, but harder than my previous ones. Also I´m not sure if i did it the right way: I used the orange gel thing to get to the ceiling button, quickly portaled to the water thing, jumped with the help blue gel to the button room, ran through buttons, somehow (I did not see what am I doing - lasers everywhere man!) picked up the cube and ran to exit.
The water and lasers are very annoying.
Please respond. :)

The first one is definitely not the intended solution for the exact reason you've pointed out, the second solution works but is slightly harder than the intended solution, although it's an interesting idea so I'm tempted to leave it in as a very minor alternative to the actual answer.

Ok. The only ways I could find to get it done are:
(1) When you enter the chamber, immediately use the fall speed to reach the button. (this would be lame if it were the intended single solution, since you can not get back up there.)
(2) Jump off the speed gel dropper, this speed is exactly enough to reach the button.
I hope i found the correct ones. =) Great chamber btw.

The easier way of finishing the first room (pressing the button through the fizzler) is the intended solution, I'm not entirely sure how else to complete that room but as long as it's more difficult than the intended solution, I'm not too worried.
You're on the right track with the speed gel and portals but it's possible to get to the cube without speed. The cleansing gel is there to prevent an alternative solution (as well as clean any items), it's a bit annoying but I remember tinkering with it and finding only one place it could go.

In the first room you can also stand on the edge near the water, pressing the button through the fizzler and catch the cube. I started with standing on the cube, just found this way easier.
I can't see how to reach the button in the 2nd room.
Need speed. Could use a path of speed gel and portals, need a cube for that. Can't get to the cube without speed. Can't find another cube. STUCK
The cleansing gel is annoying btw.
Could you tell me what I am doing wrong, without giving me (part of) the solution?
