Awesome! The sound really intrigued me and the animations were well supplemented by it. I played it a bit and got past the first ?world? and I can easily say that I'm enjoying it so far!
If this game had infinite procedurally generated levels, I would buy it for $20. I love how meditative the experience is, how everything responds to subtle movement and there's no hurry or frustration (at least in the demo levels). It's just too short.
