The game uses a side-view perspective. Casey must travel through dangerous stages, defeat enemies, collect power-ups, and reach the goal while managing a limited supply of lives and health. Levels contain platforms, hazards, secret areas, vertical routes, and teleporters that can send the player to different parts of the world.

Masks provide the main progression system. Hero forms such as Maniaxe, Samurai, and Juggernaut grant different attacks or movement abilities, while taking damage can remove a mask before harming Casey directly. The world map branches, so players can often choose among routes and discover alternate stages.

Learn what each mask does before spending it. Keep a useful form for sections that require its attack or movement ability, and avoid unnecessary damage because losing a mask can make later areas much harder.

Explore beyond the obvious route. Hidden blocks, teleporters, bonus items, and branching paths are central to the level design. When a stage seems impassable, check vertical areas and nearby walls rather than assuming the route is closed.
