Set in a whimsical yet darkly absurd world, players navigate through the fantastical city of Cardia, where emotions manifest as literal living entities. As a skilled heartsmith, your ability to forge, mend, and steal hearts becomes crucial when you are framed for the theft of the Heart of the City—a powerful entity that regulates emotions for all. You must solve riddles, engage in narcissistic debates with hearts seeking existential validation, and uncover a conspiracy that threatens to unravel the fabric of emotions in Cardia. With each decision, your character's emotional state can shift, affecting how others perceive you and what paths you can take.
