The soundtrack composer for the upcoming Scott Pilgrim adaptation (of the upcoming Scott Pilgrim movie) debuted one of the game's songs at PAX East, and screengrabs taken from that video give a glimpse of what to expect in the game.
Anamanaguchi, the chiptune punk band that purports to create its songs with a hacked NES, is handling the music. An appropriate choice, one would think. And, according to the Attract Mode blog, Paul Robertson is in charge of the visuals and animation you see here.
These 14 grabs were the best of the bunch; there are several more at the link below.
