Got through... Probably unintended...? This is how I bounced to the final area.
Hehe, this move is unintended ofc. Looks like I should have all the walls made of glass 
Hahaha... that sounds familiar to me...

[/spoiler]No wonder. You know that general idea of this map came to me while I was playing your map "Da-MaSK". So prefix "Da" is some kind of reference to your map.
Grey, I meant that I had to turn almost the entire map Da-MaSK into glass after all the unintended solutions some ppl like Shakky found! Damn gels...

[/spoiler]Another solution... Let me know!
Wow, this was one of the smartest Single player test chambers I've ever played. It took me a while to solve this, but I really liked it.
There was one thing I noticed though. In the last room where the exit door is, there seems to be a missing brush, or tile, or whatever the right term is, to the right of the observation window.
Also as a suggestion I think it would be a good idea to implement a way to get back into the last room easier after you've already been there. that way if you leave there without leaving a portal in there(and with the cube off of the button in there), you don't have to implement the solution of how to get there all over again. err I may have worded that poorly.
but anyway besides those I don't have any comments to make besides the fact that I think this map was one of the better Single Player maps I've ever played. Great job.
