In a world where emotions are tangible commodities, players take on the role of a Heart Merchant who can trade, steal, or gift hearts from different characters in a bustling city. Each heart contains a unique emotional essence tied to its owner, influencing their actions and choices. Players must navigate complex emotional relationships, solve puzzles based on emotional intelligence, and make pivotal decisions that can either unite or divide the city. As they interact with quirky NPCs, the player discovers the profound effects of love, jealousy, happiness, and sorrow, all while racing against an impending emotional disaster that could corrupt the city’s hearts forever.
