In a world where hearts can be literally exchanged, players assume the role of a quirky, heartless detective named Callie P. Heartbreaker. Set in a city where emotions are traded like currency, Callie must unravel a series of inexplicable thefts targeting the very hearts of its citizens. As players navigate through bizarre encounters—from a coffee shop run by anxious baristas who sell 'comfort hearts' to an underground black market for extreme emotions—they will engage in dialogue trees and choose-your-own-adventure elements that shape the storyline. Each choice influences Callie’s ability to 'borrow' or 'steal' hearts from others, leading to unexpected emotional consequences. With 14 potential heart combinations, players can explore themes of love, fear, joy, and sadness in comedic and dramatic ways while trying to reclaim the stolen heart that once belonged to Callie's former partner, whose mysterious abandonment holds the key to Callie's missing emotional depth.
