In a world where emotions are traded like currency, you play as an underground merchant specializing in rare hearts harvested from the bizarre and eccentric inhabitants of the city of Emo-Tropolis. Your heart collection ranges from the romantic to the grotesque, and your goal is to build the ultimate heart to win over the enigmatic and laughter-loving Heartthief. You'll navigate a city filled with absurd characters, hold dealings in secret locations, and manage the fallout from your transactions. Players must make choices that affect the emotional balance of the city and outsmart rival merchants, all while navigating dramatic purchases, humorous heart quirks, and unexpected consequences that shape the fate of both your character and Emo-Tropolis.
