Polygon Protocol: a game by Kiril Petrovski
You start as a fragile circle and evolve into deadlier polygons, each side another firing angle. Your dash is both your escape and your best weapon, so you weave through corrupted swarms and dash into exposed boss hearts. Four bosses with their own music and mechanics, Protocols that trade risk for score, a seeded Daily Protocol with its own leaderboard, a shape tree of starting forms, and endless mode after 15:00. Started as a Mini Jam 202 entry; I've kept building it in Godot 4.5 since. It plays with a gamepad or touch too.
