In a world where emotions not only drive human decisions but manifest physically as heart-shaped tokens, you play as a heart architect named Cass who manipulates these tokens to affect the lives of others. The city is plagued by a mysterious affliction—a dark fog that has begun to consume people's hearts, causing them to lose their emotions and humanity. Your quest is to uncover the source of this malignancy while stripping down to the hearts of the people you encounter, shaping their fates based on the choices you make. Team up with quirky characters, unravel twisted backstories, and navigate through a layered narrative where each decision alters the heart tokens and the emotional state of the city. Can you save the hearts of the people before your own is consumed?
