The animation is quite lovely, not my type of game though. I like some bullet hell games, but not the kind that are mind numbingly-controller-smashing-morale-crushing hard like this one seems to be.
Quick note: I've heard that while people can download the demo without trouble, they're getting error messages when trying to purchase the full game. If you manage to break through, let us (and MS) know the circumstances it happened under!
Well I'm happy to say as of 2:30 am EST the game is up and running. I haven't had a chance to play much yet but it seems really good and not too difficult. The Magic Barrier system that slows down bullets helps quite a bit and the Magic cards are interesting.
