In a bustling city where emotions and hearts are commodities, you play as 'Harley', a heart trader who can swap hearts among people, allowing them to experience different emotions for a price. While negotiating heart trades, you accidentally trade for a heart that belongs to a notorious mob boss. As you navigate through the complexities of the emotional black market, you'll have to outwit cunning traders, help desperate individuals reclaim their stolen emotions, and ultimately decide whether to return the heart or use it to gain control over the city's hearts. The game features branching narratives with moral dilemmas, multiple endings, and unique emotional power-ups based on the hearts you collect.
