In a world where emotional connections are literally tangible, players take on the role of a Heart Mechanic, a skilled individual who repairs and modifies hearts—both metaphorically and physically. After a mysterious epidemic causes people to lose their emotional cores, you must traverse through various districts, each representing different emotional states. Engaging with memorable characters, uncovering dark secrets, and solving emotional puzzles will lead you to the root of the epidemic. As you fix hearts, you also grapple with your own past traumas, shaping your character's growth and choices throughout the journey. Will you restore love, hope, and joy to the city before it succumbs to emotional desolation?
