Pretty fun game with an extremely intriguing premise, but the collision detection and controls could use some work. For example, it isn't clear that when stretching and unstretching you'll restore yourself to the far end of the direction you're stretching in. Also, having more forgiveness mechanics would add a lot to the feel of the game. I like the escalation of challenge but certain things like not being able to crouch/stretch under a narrow passageway when already pressed up against it detract from it. Overall, pretty solid idea but in need of some polish. Nice job!
