I'm not huge into puzzle games, but this one definitely kept my attention. The animation is very fluid and the physics work very well. It has a great learning curve as well, it starts off easy, but gets pretty difficult as it goes on, where you have to actually think it through a little bit. I didn't rate it a 10 because I found two glitches in the music. When I pressed the replay button during the snow levels, a new track would play over the one originally playing, instead of replaying the original one, and when I transitioned over to the new set of levels, the track from the old set of levels played over it. I was able to solve both of these by pressing "Menu" and selecting the level again, but that eventually becomes an annoyance. Other than that, it's a great puzzle game.
