An interesting take on a billiard/snooker based game, although I must admit I probably wouldn't miss it if the ability to walk was removed. I also guess there is a story here, but it wasn't obvious to me.
I liked that there was some challenge to trying not to hit certain things and to get things in their right spots. The last level felt both a funny different experience and also a bit out of place. I could see a spinoff where the main goal is pure destruction in every level. :D
I think I noticed the character's face changing in the top left, but I admit I didn't find myself looking there much.
