The gameplay of Majora’s Mask expands on that of Ocarina of Time; it retains the concept of dungeon puzzles and ocarina songs, and introduces character transformations and a three-day cycle. As in previous installments, Link can perform basic actions such as walking, running and limited jumping, and must use items to battle enemies and solve puzzles. Link’s main weapon is the sword, which can be upgraded throughout the game. Other weapons and items are available—Link can block or reflect attacks with a shield, stun enemies by throwing Deku Nuts, attack from a distance with a bow and arrows, destroy obstacles and damage enemies with bombs. He can also latch onto objects or paralyze enemies with the Hookshot. Magic power allows attacks such as magical arrows or spin attacks, and the use of special items.
