Played all your maps. I know this is from the beginning of Portal 2 and since then you probably didn't consider doing further community maps. I would have loved to see you making pure no elements maps.
This version of your second one turns out to be the same difficulty after all. I was thinking it's an advanced version with higher difficulty, but it's just an alternate creation with some different elements.... I was expecting a braintwister with the upper portal surface since it seems impossible to keep the portal and return to the main room at the same time. But then the exit area opens up. Well, this was close to a disappointment tbh haha :-P
Btw it's a shame you do not give any hints in the comments! Not to help less experienced players is not ok.

I haven't worked so hard in a while. Did most of it twice before I finally figured it out. The solution just escaped me and I wandered the halls scratching my head. Good puzzle. Good design too. #F4F my maps

UPDATE rev 3: Removed a few more cheats and made several improvements that make the chamber play better. Hopefully you will agree. The EYE... look me in the EYE! You WILL agree!!! (waves arms dramatically)

It's always better to make the intended solution clearer, as you just did. Can't be mad at this chamber though. :)

UPDATE rev 2: Removed several cheats and an alternate end. @toncica, Thanks for enlightening me! I think it's better now; and by better I mean as maddening as it really should be. :-)

Got distracted before I started the third map and it shows. Maybe this one was a little tricky anyway, so running in circles was adequate.
