Music is good. It's quiet and relaxing, leaving no place for boring silence, yet not distracting from actual gameplay. Some may call it mainstream, but I like minimalistic design when it comes to puzzle games, so user could concentrate deeply on devising level solution. Relying mostly on neutral colors, fluent movements and smooth forms, visual part of this game suit well to the music.
There is no tutorial, and that's good! Good puzzle game is one where user can grasp rules by himself without prolonged explanation. This game does fine job with it, carefully introducing new features to the player on easy levels, then presenting actual puzzle. Personally, I also like that levels are not very challenging, as it allows to think through all levels fully in advance.
