It's a directional pad music game, that's the best way to describe it
The main story is that in the futuristic space community that lives in Twin Ships and dancing is banned, so this rebel group and a dance professor are trying to stick it to the Emperor by breaking the rules and dance, if it sounds silly that's what the developers where going for and the game is fun in that sense. I just beat the game and it wasn't that hard to be honest, it took me a few tries to get to the end. I'm sure I'll never pop this title into my PlayStation again.
