Gameplay

Play follows a traditional role-playing structure. The party explores the island on foot, and the player fields three lead characters at a time while swapping others in during travel. Fights unfold on a grid battlefield where attacks can target enemies directly or strike obstacles to inflict damage. A timing mechanic rewards a well-pressed button at the moment of impact with bonus damage or the start of a combo, up to a maximum of four hits.
