Was not expecting to see a bullet hell boss for thsi theme, but it's an interesting idea. Though I don't really see the theme in it, it is a cool mechanic to make the focus be on staying in a certain area while avoiding the bullets. Though obviously the bug makes that a little less useful. That and the difficulty is SUPER fast in how it ramps up which had me surprised.
Though I did get somewhat used to it, was still VERY surprising when I landed the first hit on the boss and the huge difference in it's attacks. Overall though a bit vague on the theme but an interesting setup and a pretty cool boss fight throughout.
