In a city where emotions are commodities, players assume the role of a 'Heart Collector,' tasked with managing and trading human emotions while overcoming a chaotic underworld of feelings. Each heart offers unique narrative paths and choices that impact the characters' lives and the city itself. The player journeys through various districts, each personifying different emotions—joy, sorrow, envy, rage—interacting with quirky characters and engaging in intense dialogue. Players must balance their ethical dilemmas about ownership of emotions against the backdrop of an ever-changing social landscape. Will you hoard hearts for power or give them away for love?
