Having a boss fight that attacks with music is just... SO GOOD ! The only thing really holding it back for me are the controls. I feel like the standard walking speed should allow you to avoid projectiles, here it feel way too slow and frustrating. Also i would have prefered a single control scheme, like move and dash with the mouse, of move and dash with the keyboard, it feels a bit weird having a non-directional button assigned to the mouse chen the game is played on keyboard. But maybe that's just me.
