What is ONE BTN BOSSES?

A 2D, single-player bullet hell game about Ace, an unpaid assistant fighting their bosses for fair pay. Your ship circles each boss automatically; you reverse direction to dodge attacks, but fewer reversals build speed and increase your firing rate. Progress through handcrafted campaign levels or face randomly generated bosses in a separate roguelite mode.

For you if...

+you enjoy learning attack patterns through repeated attempts
+you like experimenting with different weapons and movement styles

Not for you if...

−you want relaxed combat with little need for precision
−you prefer exploration over a sequence of boss fights
