Interesting playthrough, thanks for recording it. Gave me a few pointers for next version
This was a really interesting and well thought out map. I liked the moving gel dispensers, but I really wished there was more of a puzzle to that.
Although I am impressed with your skill and timing to use the pre-recorded lines from the actual game, I was not impressed with your over usage of these. You chose lines that are VERY memorable and not generic enough to be re-used without destroying the immersion that you're trying (and for the most part succeeding) to create. I did however like the cameo of the coop bots. Nicely done there.
As for the puzzles, they were straight forward and yet took a bit of thinking to complete. If anything, too easy, but still fun. Also your theme execution (visually) was excellent.
I had a problem with the map crashing when I tried to quicksave though. I've never had that problem, so you might want to take a look at any save related scripting you've got going and see if you can resolve that. I had to restart my game 3 times, then noclip back to the last chamber, and by the time I gave up on trying to save, I solved it and realized it was basically over anyway.
Great work! Keep it up.
Thanks Ratboy. The save crash is because the level is too big. I need to get the last room into a new level with a brand new test chamber and separate both levels.
Regarding the puzzles, my goal is to make levels that look like an alternate Portal 2 branch, yet fit within the Portal 2 experience. So they should be as "easy" as the Valve ones, but take place in a new universe. With this level, I wanted to explore the possibilities had Wheatley taken Chell into the start of the coop levels when he discovered the robots.
This was a fun map. I think the test chambers were well designed and easy to solve, perhaps too easy.
I think I found a bug: My first time in Chamber 2 I believe that the funnel failed to reverse when the redirection cube was in place on the pedestal. I remember seeing the funnel was turned off so I solved it similar to how djinndrache did.
Then I got to the third chamber and got the cube in place, but I wasn't sure about the final fling and that's when I ran into the previously mentioned quick-save error. When I was making my way back to chamber 3 I saw that the funnel in chamber 2 did reverse as it should so I solved it as I believe was intended.
P.S. even though I agree that the P2 dialogue was over used in your map I like that you added the ability to
You did miss them then 
Got a save buffer error whenever I tried to save. Button in first chamber also got "bouncy" and couldn't stand on it to activate funnel. Errors....
Long and big but unfortunately not challenging. Voices seemed a bit random. Sorry if that feels overly critical - I did enjoy it while it lasted.
On saving I got a buffer error, too (and the game crashed). Too bad, as the map looked promising.
I cannot play a game without Saving periodically as I go, and I could not save without crashing.
So I gave up. Why didn't you fix it as promised ?
Still occupied with some much more important mapping. I may just delete this submission
