The purpose of the game is to knock the other player into a sewer manhole. There is a 99 second time limit, and the player has a set limit of stamina (200), both of which are represented by numbers. The player has two types of attacks: a light punch and a heavy punch. The light punch does not push your opponent as far as the heavy punch, but it is harder to block. The heavy punch sends your opponent reeling backwards, but can be blocked easily and takes a bit longer to pull off. (wikipedia)
