In a world where human emotions manifest as physical entities, you play as a heart tamper—a rogue emotional mechanic. One day, you accidentally swap hearts with a powerful figure in a shadowy city ruled by a mysterious organization that feeds on fear and despair. As you navigate through chaotic districts, dodging mercenaries and uncovering dark secrets, you'll encounter various characters whose hearts you've swapped. Each character represents a different emotion, and you must solve their personal crises to regain your own heart and restore balance. You'll face moral dilemmas about empathy and the true nature of emotions, making choices that affect not only your fate but also the city's. With multiple endings based on your decisions, the game explores the depths of the human psyche while delivering an engaging narrative—a wild ride through the tangled web of feelings, fears, and the occasional heart-wrenching pun.
