Nice work! The presentation is great on this - I love the monochrome aesthetic and the little character portraits, and the bullet hell action has some nice crunchiness to it. The spells were a little bit confusing to me - I didn't quite get what the benefit of something like "rotate CCW" was - but eventually a new wave started that made me just explode bullets in every direction and that let me finish the hero off. (Is that a failsafe wave, or did I get lucky?)
I wonder what the hero's Plan B is. :)
