A top-of-the-line puzzle game to this day.

The spritework is lush and gorgeous, bringing Lip and friends' fairy world to life in style. The music is memorable and charming. And of course, the gameplay: it's a brilliantly intuitive tile-matching game with a very precise and gradual difficulty curve. It gets the "low skill floor, high skill ceiling" angle totally right while being consistently encouraging to the player.

Seriously, you should play this game if you haven't. You can play the game in Japanese on NSO, and there's also a translation patch out there.
