Colour Break is a match-3 puzzle game with level and endless modes, scoring, stars, and a menu/HUD for settings and bug reports. It is built as a single game component that renders a 2D board in 3D, handles mouse, keyboard, and controller input, runs the match/clear/collapse/refill state machine, and uses a Razor UI for menus. Progress and bug reports are stored locally in Game.Cookies using small helper data models and stores.
