Finger-tappin' goodness.
Wow, this is truly amazing. The sound was fantastic (it helps that I'm a metalhead). The fast-paced emtal riffs go perfect with this game. It's very original though, and having the scene going on in the background was cool, too, even if I couldn't pay attention to it the whole time. The only probably I have with it is the button-prompting icons. I think that every arrow should have a different color; it would help distinguish them.
