Seems to work well, no bugs encountered. Maybe a larger screen, and some larger moving objects would be nice, but I never got too deep into bullet hell games, so take my opinion with a pinch of salt.

I think the hitbox should be more in the center, I'm unsure where it is right now. And maybe a bit smaller? Other than that, maybe the laser shot needs some balancing, it really rips through everything very fast it feels.

I liked the look of the second stage a lot, the tall grass and the parallax made it look especially nice.

Boss-wise I liked the stage 1 boss the best, that final pattern was really cool! Bomb has a cool feel to it too, the shield plus dropping glaciers combo feels very powerful.
