I suck at bullet hells and got stomped by the second boss even after trying for quite a bit. I like the idea of a time based health pool and the first boss is awesome and I enjoyed learning it. I do hate the fact that you need to beat the first boss over and over and over, I would split the game into a hardcore and normal mode, where in the normal mode you get a checkpoint for each boss and can just focus on the one boss, and then try your hand at hardcore where death brings you to the beginning. Other than that no real complaints, I like the art and the menu is good so far.
