Good stuff. Strutter is the standout song, imo, followed by YYZ. Shout at the Devil and You Really Got Me are both okay, but suffer from I Love Rock and Roll syndrome--while nice sounding songs, neither is really complex and mostly breaks down to the same two patterns over and over with some perfunctory solos. They're both "first tier" songs according to the released MTV list.
Played some co-op with my roommate, and the per-player difficulty selection is great. Wish you could select parts during guitar selection, though; it's annoying to have to swap all the time depending on if you want lead or bass.
There are two characters, two guitars, one bass, and one arena in the demo. Psychobilly Freakout and Who Was In My Room Last Night both play on the menu though neither is selectable--get those PAR codes working, guys!
Training isn't available so I dunno if it's possible to pick lead/rhythm/bass on 1-player. Hope so.
Anyone up for a demo-based high score competition?
