Cool game with very nice beats to go with! Plus cute girl is always a plus. This game definitely has that rhythm/bullet hell charm to it which is rarely done all that much.
A bit of feedback is that the game has a slight consistency problem with trying to time parries and dodging bullets, as bullets move according to the beats of a song, and playing the game while relying on just the beat can get frustrating. Having a small indicator to when the next beat is going to hit could help so that players can better maneuver the beats of the song. Plus, this won't necessarily take the challenge away from the game since it is a bullet hell after all,
