I came to know this game after seeing the lore room in Rogue Legacy. I've enjoyed this flash thoroughly, but I have to agree with some other people out there, that the game is quite easy compared to other bullet hell shooters. Most levels I beat with only one try. Some of the harder ones I had to try 2 or 3 times before I could read the pattern... However I do love how they mixed a rhythm game AND a bullet hell game, which I am a fan of both.
