That was really really clever ^^ I started that puzzle after almost 2 years without playing Portal 2 and the first puzzle blocked me four about half an hour X) Then I checked the comments on this page, and figured out the solution using the fizzler :p
The second one was a bit more straight forward but still well thought, and I think throwing the cube was probably not the intended solution for the last one but I was a bit lazy on this one...

very cool and very clever. Excellent design! Thumbs up!

hahah thanks for finding that exploit, it really made me laugh

Хорошая головоломка.
Когда я проходил головоломку в первый раз, то в первой камере не использовал fizzler как задумывалось автором. Только прочитав коментарии я нашел решение автора.

Good puzzle.
When I was a puzzle for the first time, the first chamber is not used as intended by the author fizzler. Just reading comments, I found the author's decision.

For the first part, you need to take advantage of the fizzler. The piston platform is there in order for you to do this :)

Allright, you got me. I have no idea how to solve even the first part now. Tried it for a while, got nowhere at all. In fact, I noclipped to the second part and to the third part, but I got nothing at all. So, you win I guess. I'm not very good at these.

Hahaha, I can't believe you managed to not follow a single step of the intended solution. You certainly did your job as a tester. Your discussion of the glitch with the panels was interesting, but I think I'll do something about it with Hammer anyway because it's really obvious, I just hadn't expected anyone to actually use it instead of solving the puzzle. I'm going to update it now so if you're curious what the actual puzzle was, you can try to solve it now that you can't do all the cube tossing stuff :)

I played your map! Watch the video here: http://www.youtube.com/watch?v=XMQjjWO00is
Summary: Refreshing, simple map. A couple of elements there that I did not need to use. Some confusion. And an unintended solution or two.

That is an excellent chamber and the last room is funny: I took both cubes because I tought in one particualr solution, but it's much much easier!!!
When you have the time try this one (not as difficult as this one of yours):

thx

Great chamber. The first part had me thinking for awhile, great job.
