It's a very unique aproach to a bullet hell, not bad mechanic wise, but some small improvements could make all the difference in this game. The game-over audio is a bit weird, don't feel like it matches with the tone of the rest of the game. The main menu could really use a different less saturated color. When the rest of the game is in this black background, the super vibrant pink is just out of place. And last but not least, please change the camera so that instead of being centered on the player, the player is on the top of the screen. I never have any reason to look above my character, so it's just wasted space.
Not that bad otherwise, had a fun time playing!
