The gameplay revolves around exploring various islands, including Wyndaria, and using the ship to visit other islands. The player can upgrade their ship and unlock new features over time. Battles are turn-based, with options to use physical attacks, magic, or defensive moves. Players can also engage in mini-games, trade items with merchants, and solve side quests to earn special hearts. These hearts, which change color depending on the emotion they represent, help Kaguya regain her emotions and unlock new areas of progress.
