A brutally honest review.
Well, the only reason you really get a four is because I like tenacious D, however your actual game is awful.
Graphics: Really bad, half of them just stolen from Tenacious D or traced over a better image.
Gameplay: Decent enough. A few bugs, such as arrows too close will glitch and automatically say Miss or Too early when you hit the first arrow. The actual arrows hardly sang up to the song either, it was a pretty awful stepfile.
Sound: Only good thing.
Originality: None.
Overall, I gave this game a 1. Get better.
