The player takes on the role of a 5th-grade boy who is accidentally warped to a fictional island called Endonesia. The protagonist must communicate with the island's 50 sealed gods in order to return home. The boy does so by obtaining several abilities called Emo powers, which draw on his emotions, and the emotions of those around him. The game features day and night cycles as well as days of the week, with the island stuck in a 10-day time loop.
