In a dystopian future where emotions can be harvested and traded, you play as a Heart Broker, skilled in the art of negotiating feelings. Assigned to investigate a string of heart thefts, you must navigate a city rife with deception, intrigue, and the occasional satirical romance. Each choice you make steers not only the fate of your own emotions but also the hearts of those around you. The game challenges players to piece together clues by engaging in clever dialogue, solving emotional puzzles, and forming alliances based on the unique 'hearts' they collect, all while managing your own heartbeat meter, which fluctuates based on moral decisions.
