Glad you liked it!
Did you try any of the other control schemes? I added a click to move control scheme and a WASD/arrow move control scheme because I was worried that the mouse control scheme would be too hard to learn, especially for people who are used to traditional bullet hell controls. I personally think that the combination of speed and precision you can get with mouse control mode makes the game more fun, but it's definitely still possible to beat the entire game with either of the other two control modes (on normal mode, anyway; hard mode might be a different story).
