This is an awesome little game with a very neat gameplay mechanic! It fits the theme well, and there's so much even though gameplay is just a minute.
Minor criticisms are that the music sounds a bit too fast and complicated for this style of game. Though complex music is great for a puzzle game, lowering the tempo a bit I think would add to the relaxed feel while maintaining the complexity the leads to it being a good puzzle accompaniment.
Graphics are simple and cute and fit the game great, with the little shapes floating in the back.
Excellent work! ^_^
