In a dystopian city where each citizen's heart is replaced with a mechanical version, you play as a heart thief. Your objective is to navigate the underbelly of society while decoding the mystery of stolen human emotions. As you interact with various characters, you'll face morally ambiguous choices that can change the heart you're after — whether it's the heart of a corrupt politician, a brilliant scientist, or an innocent child. Each choice deeply impacts the unfolding narrative, leading to multiple endings based on the emotional connections you forge (or break) throughout your journey.
