Fun game! I really like how it's basically all boss fights as those are much more interesting in my opinion than just hoards of simple enemies in a bullet hell. A few things I think would make it even more fun to play might be not to have movement speed be a debuff (it's feels like it's pulling away from player enjoyment/ability, making it harder to dodge bullets. Maybe an alternative would be higher enemy damage, so players can still use their skill to outmaneuver, but a mistake is more costly). Also maybe different bullet sprites for bullets that behave differently, like the (epic) centipede boss's bullets that kind of bounce back and forth. It was hard to tell which bullet was going to come at me, and which was going to do the wavy thing, making it hard to judge where I should move. Those are just my opinions though so take them with a grain of salt. Overall a nice submission, way to go!
