Not bad, it could do with a bit more variation in all area though.
Sometimes there wouldn't be anything new in the scene and it actually looked like you are standing still which kept messing with me. The music was quite plain and repetitive, I think you could have found a much better track suited to your game with a little looking in the right places as well as a sound effect for your character.
The programming itself was pretty solid, I didnt get any whacky physics going on when being tipped over by ramps etc
