The game, which largely follows the action RPG and hack and slash gameplay of previous games in the series, sees players alternate between the roles of Sora and Riku, which is done via the 'Drop' system. During gameplay, a Drop Gauge gradually depletes over time, though it can be replenished with items. When the gauge completely empties, control will switch to the other character, though players may also opt to drop manually at any time. Drop Points, which are earned by defeating enemies and completing optional objectives, can be spent on bonuses that can be used until the next time the character drops, such as a slower Drop Gauge or increased attack or defense.[1] The game reuses the Command Deck system from Birth by Sleep, in which players can customize a deck filled with various actions, spells, and items that can be quickly selected. There are also several new elements added to the gameplay. Flowmotion allows players to move quickly about by performing actions such as bouncing off walls, grinding on rails and spinning around poles.[2] Reality Shift is a system the player can use on certain objects or weakened opponents. It involves a touch-screen activated minigame unique to each world, which includes dragging the screen to fling a target like a catapult, touching hidden words to take control of enemies, and playing a rhythm-based minigame to cause fireworks to appear.[3][4]
