Well, I picked it up. First impressions? Amazing! We haven't had puzzle gaming this innovative in years. You can really say you've never played anything like it, though it's still familiar and easy to pick up. But the art and sound design is really what pushes it over the top. It's a great little package. $30 seems like a good deal.
EDIT - Also, having a plot in a puzzle game is really great. The story segments are fun. Short, often humorous, and with some great quirky, dark art. Good voice acting, too. It really keeps you moving forward (though I'm enjoying trying to go back and "master" each level with the trophy mode... which basically just means "do this level 100% perfectly in under xx seconds").
