In 'Whose Heart Is It, Anyway?', players find themselves in an absurdly dark situation after waking up in a bizarre carnival ostensibly hosted by a mysterious entity known only as The Matchmaker. Instead of typical carnival games, contestants must engage in twisted challenges related to dismembered hearts that are found around the grounds. The hearts belong to the attendees, and through dialogue, exploration, and decision-making, players must solve the mystery behind the carnival and unearth the connections between the hearts and their owners. The game combines humor and horror, with players piecing together the untold stories and secrets of the characters they encounter, ultimately leading to a shocking revelation about their own heart.
