Gameplay
Choose between six modes of accelerated gameplay, each complete with original quests, enemies and attacks. Hero Mode consists of random battles with classic RPG leveling-up elements, Evil Lord Mode involves a high degree of strategy to summon the appropriate monsters against the varying oncoming enemies, Princess Mode involves fast-paced shooting action as you guide the princess safely to and from her castle, and Knight Mode challenges the player to protect the sage in any way possible, including carrying the sage away from danger, clinging to monsters to halt their movement, or even throwing yourself at enemies to cause physical damage. Each of the gameplay modes contains 30 stages in which players have 30 seconds, or a half-minute, to complete their tasks. Retaining the charm inherent in classic RPGs, Half-Minute Hero is a breakneck foray into an ancient land of monsters and magic, 30 seconds at a time.

There is also a limited multiplayer mode in which two heroes can fight to complete a quest before the other. The multiplayer mode features three stages in which the two players will fight to collect power ups and level up in order to fight the Evil Lord at the end
