Really good Bullet hell movement, dodging everything just feels really good! (suck at the platforming tho xD)
Gameplay
Overall, it was very impressive! the gameplay of bullet hell and precision platforming mixed in a way I couldn't even imagine!
The difficulty curve was a bit steep, and this would mean you visit the progression much more early in the game, I didn't feel like I played enough! And only later then, levels would bring you into more into that kaizo strategy pacing.
This is just a suggestion, but enemies I feel can have some more novelty, at first, they are very satisfying to shoot up, but they become kind of annoyance later on. A progression system of sorts could possibly be given for killing enemies(or scoring system).
Visual/Sfx
I do think there can be some impact sounds/feedback, like when the player lands or grapples the wall, walking sounds as well. but these can be very quiet still, the sleekness of the player felt nice that way!
