It is a non-linear map which have many paths to take and reach the end. The point is, that you play a map one time and you are happy. Then you have a little break in Portal, because there aren't any new released maps for some time. But the answer is here: play the Deja-Vu again, but choose a different path with different puzzles. You can choose freely the way that is going to lead you to the end. Thats it!
The Choice is in your hands...
I choose escape because its a TRAP , i think.
nice work..i would choose "escape" too..'cause i can buy a cake in supermarket xD

I'll just noclip through that hole! :D
Looks like there is a big Mirror in the middle of the Room XD
when i picked cake ye... i puted portal up somewhere and somehow i got to the cake and it was ******* plastic >.< lol
I would most likely try shooting portals in that hole in the ceiling before chosing
