Ahhh, rhythm games. I love these.
The game's execution was pretty interesting. I did get thrown off a lot by the fact that the left side only had 2 buttons, and the right had 3. Though, I guess I just didn't read the directions well enough.
Though, I think this game could have used a bit more polish. Sometimes, buttons didn't register, notes I thought would be perfect would be weak, and I don't think that metal guitars would make that nice of a "guitar" noise from Animal Crossing. Just a nit-picky thing; don't take it too seriously :D
Overall, this game's direction was in the right spot. The arcade sense was absolutely there, but I think it overall could have used a few more levels or maybe even a new mechanic with bonus points. No offense at all; your game is great. With more polish and content, it would be even better, though!
I'll provide it a 6/10. It's a game with potential, and I hope to see more of your games!
