It would be a lot nicer if it didn't stop you when GLaDOS talks. Also, if crawling up a wall to a corner automatically made you move onto the corner, instead of you having to jump.
I did, but the audio would layer its dialogue when the player finishes the level quickly, and if I just made it stop It wouldn't make sense, and yes, the wall climbing is kind of a broken for now, I'll probably fix that, no promises.
