In a realm where feelings are physical entities, players take on the role of a Heartkeeper, a mystical being tasked with the collection, trading, and management of hearts—each representing an individual's emotions and memories. When a nefarious force starts to steal hearts and wreak emotional havoc across the land, the Heartkeeper must journey through whimsical and perilous locales to restore balance. Players will interact with quirky characters, confront their own suppressed feelings, and make challenging decisions that will shape the hearts they possess and the world around them.
