In a world where organ transplants are managed by a whimsical bureaucracy, players find themselves in a surreal city where hearts are not just physical organs but metaphorical representations of personal traits and secrets. As a Heartkeeper, you must navigate through colorful characters and quirky situations, collecting hearts from various townsfolk, each with their hidden agendas. Players interact with NPCs, discovering clues and engaging in mini-challenges, as they attempt to piece together who truly deserves each heart. The ultimate goal? Unravel the mystery of 'The Harnisher', a rogue mechanic who steals hearts and leaves chaos, all while dodging the eye of the Heartwatch—a hilariously inept but overzealous organization that protects the city’s emotional balance.
