Me likey! I found this game called Amped Up (Credits go to whoever made it). It's pretty cool. A college (high school?) -made game, sort of an imitation of Guitar Hero (now who doesn't enjoy that game... despite it's difficulty, at least for me?)
Play the game here.
Not very many choices, and I'd actually prefer a Miniclip imitation-like version, but if ur plain bored, 'tis fun.
