Great game. The mechanic feel fine tuned and the design is very clean. I think the main thing the game needs is just more glamour. I want to really feel like I'm bullet hell. So more pumped music, cooler visuals, and snappier sound effects could really pump it up a notch. One small thing that could also help is replacing the cursor. The generic mouse cursor covers things up, it's pretty easy to just replace it with some crosshairs.
