I like the artstyle

The character design remind me of BFDI. Nice game!

i understand the minimalist controls your have by having the player follow the cursor, not many bullet hells do this because you're also shooting stuff but it's a nice way to give players more precise control without messing with speed (if you were to use buttons for movement that it is), but i find that im wrestling with the controls because you want to be avoiding bullets by routing the cursor away from the bullets but at the same time you want to put the cursor on the bullet (the enemies that you have to click on to kill), and so there's a contradiction on what you want to do with the cursor, i think it leans more towards the "move towards the bullets" side because if you don't deal with the enemies they'll add up overtime, i think you went too hard on the minimalist controls

in terms of being a bullet hell you could have shrank the hitboxes of the player and bullets, you're able to be hurt by the tail of the fireballs which doesn't seem right

overall, interesting hybrid of a bullet hell, though could be executed better
