The game contains 103 levels, varying wildly in difficulty and size, although the player is free to choose his own path through the game. The game was re-released as a part of Sonic's Ultimate Genesis Collection (360/PS3).StoryThe story is a throwaway plot, like most platformers at the time. A new game at the arcade can simulate reality; everything is all fine and dandy until one of the bosses, Heady Metal, begins somehow imprisoning those who lose within the game. Players control a sunglasses-wearing kid, who has been called upon to venture into the game and defeat him.GameplayThe game is a platformer that includes the concept of masks - powerups which enable all sorts of powers. One of these forms is a knight who can climb and break blocks beneath him by jumping, another is a hoverboarder who can change the direction of gravity. The levels are organized in such a way that these are required to pass through the game, often incorporating two separate paths based on which mask the player is wearing. The game includes four bosses - each manifestations of Heady Metal.
