(This used to be called Sequence, but then legal happened.)
This game is hard. You're beatmatching attack, defense, and magic all at once. I never managed to get far, and I'm fairly good at rhythm games. (But, I'm pretty poor at RPGs, so that could be a factor.)
Helping the game is the fact that it has a very self-aware style. There's plenty of meta-humor, but it's not just to mask a weak story or anything like that.
Soundtrack is all music by Ronald Jenkees and Michael Wade Hamilton.
There's a sequel, There Came an Echo, which is a voice-controlled strategy game. So, these guys definitely like to mash up genres.
