In a world where people wear their hearts on their sleeves—literally!—players venture into the vibrant city of Emotropolis, where each resident's emotions are represented by unique, colorful hearts. You’re a quirky, rogue Emotion Merchant specializing in trading hearts. One day, you stumble upon a rare heart that doesn’t belong to anyone and unlocks the ability to feel the emotions linked to it. Players must navigate through a web of colorful characters, each with their own emotional baggage, deciphering clues to discover who the heart truly belongs to. Choices affect relationships and the city’s fate, leading to multiple endings based on how well players connect with the residents and resolve their emotional turmoil.
