I enjoy the hell out of this game, it is easy to learn, but hard to master. And, as I find most important for phone games, it has a surprising variety in gameplay - with different goals, which unlock characters with new abilities. And, something I never knew I wanted, a game with calming music and beautiful visuals and scenery. Unfortunately there's no way to "win" that I know of (it's an endless level until you die), but that's my only complaint & I enjoyed everything else. Worth your download.
