Just Fresh Enough
9 only due to lack of music.
You didn't try to venture too far away from the traditional rhythm game, but you added enough to make this a very difficult yet extremely playable game.
Unfortunately, your "health gauge" isn't my idea of a good thing to do. It doesn't stand out enough. What I think would be better would be the guitarist bird to look more damaged and to blink based on your hp level. Of course if someone is sitting next to you, they're definitely going to be letting you know about it >:)
