WOW Cobra! That was amazing!
I recorded a blind run, not a solution video, so it's around 20 min. I'm having problems with Youtube today and failed to upload 2 times... I'll try again later!
OK, this was a very nice map! Was really funny and fairly long overall, congratulations! 
I liked much the puzzles even though they were not too difficult for my kind
For the first chamber solution, as you'll see in the video, I missed the white portalable wall at the uppermost area so I tried to figure out a really twisted way to get the cube there first and me later (to no avail though)
However, I rated it 4/5 because some easy-to-fix stuff (I feel kind of outdated after watching how cobra destroyed it, but still...):
suggestions for a fix
||1. There is a problem (that you'll check in the video) with a savepoint near the floor button with the "square" signage in last chamber, I had to nocllip as when it fired the saving i was falling in the goo

In last chanmber there are many possible exploits... more of them after watching Cobra's vide. One of them you'll see in the video: there is no need for the rotating panel (square signage) as you can do the multiple flinging maneuver and shoot a portal on last elevated platform... easily fixable by extending annother glass window there!

The general feeling with the puzzles were that you had to search a lot to understand what was each thing for... or where to head to first... I guess some more indicating signage would be great. Also you could create a custom signage for the turning catapults... For example in chamber 1 I went right to the upper floor to get a cube as the signage suggested, but I couldn't since I needed the other one in first floor reach the second cube...

I've seen that you ignored some of the suggestions at the TWP showcasing thread. Overall the button's frames would be necessary. Don't you like them or what?
I think I only saw a couple of buttons with frames... I think all the rest is pretty much detailed and I liked the lighting as I already mentioned

Dispite those tiny things, the map is really good!
Thanks for creating!
