Awesome awesome awesome game, loved the visuals going along with the music, and the bullet patterns were super satisfying to dodge, although I would have enjoyed a focus mode/button that slowed down the movement. I think there was probably a missed opportunity turning the confinement zone into a NCS style super visualizer :P
I think the difficulty was spot on, although maybe I would have enjoyed a smattering of phases with more slower bullets instead of the fast ones, and maybe more patterns that made use of the confinement zone, like the purple ones that looped around inside in level 1 i think? And maybe might have liked some feedback on whether or not shooting things does anything, although I'm completely fine with just one hand WASD dodging since the visuals are so sick.
The overall polish and game feel of the levels was super cool, amazing work! congrats on the submission :)
