My attempt at combining the rhythm game and bullet hell genres. This game is VERY hard and can feel impossible at first since you have to survive a bullet hell while staying in sync to the bpm of the music.  Like most bullet hells the key is understanding the bullet patterns and then figuring out how to weave through them while staying at the right tempo.
