Not that good.
Graphics - A lot of times the sync was off, which is a crucial factor to games of this genre. Anywhere short of seamless doesn't cut it.
Style - It's a copy of something else, so rightfully, it doesn't earn any of it's own style points.
Sound - Good sound. Liked the music.
Violence - No violence whatsoever.
Interactivity - Good, responsive keys and a workable layout.
Overall - Graphics bring it down a lot. Without seamless synchronization of the arrows with the music, games like this just get frustrating.
