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!

nice very
And did u found out how to make the Pipe ?
Finally some water :)
Ah I recognize that from the Escape levels.
Oh dang, the water is gorgeous. Did you tweak it at all? Doesn't seem like normal Source water.
Nice render. You use new texture for the water ?
Nope. It's the orginal water from Source SDK.
wait make the walls notportalspawnable because if the player fires a portal in the water the water will be splitten and buggy.
Aw... I wanted to test Portal 2's Water Physics once I installed it on my computer... if it will even come out.
