Half-Minute Hero's single player mode features 6 different game modes. Each mode is based on one part of a larger story, and as such, the last three modes are not available until the player has completed the first three modes; these last three modes are then unlocked in order after completing the previous mode. Each mode centers around a mechanic based on a limited amount of time (normally 30 seconds as implied by the game's title) to complete that part of the game.
