Your game is gorgeous! I play it on my now iPod 4S, and it is like staring at a frustrating jewel that only makes you think, and does not let you get away with accidental rubbing.
For a couple of weeks it kept me up while I try to get a perfect on each level, and I would always be switching worlds when anyone started to frustrate me. Still, it is very meditative.
Is there a way to play the pixel art version? I think that would be a fun way to revisit this game.
