Cool game, unfortunately I got stuck behind an open door but I could see the "Thanks for playing" screen on the other side of the wall it clipped me through so I'll count that as a win :P
Seriously though this looks great and feels great for the most part. The physics feel a bit off in places, I think largely because you don't conserve momentum so you come to a dead stop when you stop pressing a move button. This led to me undershooting a lot of jumps because I expected momentum to keep carrying me forward while I was in the air.
