In a dystopian world where hearts are a currency, you play as a heart thief who steals hearts from the living to sell on the black market. Each heart has its own unique memories and emotions, which you can relive while navigating through various scenarios. Players must carefully decide which hearts to steal, manipulate their emotions, and confront the consequences of their choices—all while being pursued by a mysterious figure known only as 'The Collector.' Can you gather enough hearts to escape your own past, or will you lose your own in the process?
