[Released] Cassata Chamber 01
Link: dload.php?action=file&file_id=94
3 weeks in the making, here is my first ever released level for Portal. A level with some rather unique and difficult challenges that force you to think differently as opposed to having lightning reflexes.
The map takes place in a standard test chamber, assuming that Glados doesn't attempt to kill you and that you just continued through the test chambers.
Looking for a lot of constructive criticisms on my very first released map so I can make some better ones down the line. Tell me what you think! Thanks. 
Edit:
Please Note: This level has been played through and completed dozens of times by 3 different people including myself.
The feeling of having cheated or exploited the map is generally intended for some parts of the map.
My puzzles are specifically designed for players who feel they are capable of completing difficult (but logical) puzzles with as few obvious hints as possible. This usually leads to puzzles in which the only possible solution is to apparently "exploit" the map, as such the case in the last test chamber for this map.
Finished map. Nicely done.
I had no real problems this map. It looked nice, it had interesting yet challenging chambers.
The only thing that I had a sort of problem with, was the final chamber. And I'm pretty sure I did it wrong. To a point where I'm not sure you could fix it.
I'm pretty sure I missed something rather significant in that room, as I couldn't figure out any other solution to it. Unless I did it right, in which case I think you need to give more direction to that solution.

You did the last puzzle EXACTLY how it was supposed to be done.
Note:
Edit:
I updated the map so that the last chamber has some hints as to what you should do.
I did it a lot differently... using the companion cube a lot more than just leaving it on the same button.
yeah thats the solution I was going to attempt before I came on and read it but it just seemed like too much work to try for something that I have never remotely seen done before in any map.
Aware and still respecting that I asked for critique, would you say that's a compliment (not being done before) or not. It could be taken both ways. 
I tried to make my puzzles as unique as I could, and this experience right here showed that maybe with the original ideas, I should give more hints as to how they're done. I'll do that next time. 
I thought it was great, one thing you could do... is in an unfinished area before that puzzle... have a door jammed open with an object, maybe a cube but it doesn't have to be... that could put the idea in peoples heads faster
Just played it again after the updates.
While I don't think the clues that you've provided will immediatly give away the solution, I think it will definatly help. So that should be good enough.
One thing I forgot to mention. In the first room,
