I played Ren_Test 2 yesterday, and wasn't overly impressed. The problem with a rotating room in a game like Portal, is that if the puzzle is any good or if the fling is challenging, it is going to take several tries. It got to the point in Ren_Test 2 that I was really sick of watching the room flipping animation. I knew exactly how to complete the map but was one attempt away from just quitting because the energy ball kept blowing up on me. Luckily, I finished on that last attempt ^_^.

My advice is that if you are going to make a room rotate and have the animation take a while, don't put any form of timed puzzle in.
