Condenses the MMO raiding experience into a bite-sized bullet hell that's five thousand times harder than any raid I've ever done as a prog raider in my entire raiding career. I love it! Simple rotations and complex item interactions means that no two runs are alike in builds, and since it's not an MMO you don't have to grind forever or get 20+ of your friends to play in order to enjoy it. Excellent stuff. Reminds me a little of Suguri and Gundeadligne, two of my favorite doujin games, to boot.
