Nice game and great idea, I just would take a special care with the movement now, because the velocity and acceleration is too slow and maybe the jump is a little bit low, I cant really appreciate jumping in things and keeping balance now, and I think the is about that, I'm sure that with a more dynamic movement the game would turn out really fun and maybe into a full game.
