In a world where hearts are literal objects that can be stolen, exchanged, and traded, players assume the role of a witty thief named Cass, who specializes in the underground market of hearts. Set in a sprawling steampunk city, players must navigate through complex social networks of heartless aristocrats, con artists, and jaded vigilantes to reclaim Cass's own heart, which was stolen in a heist gone wrong. As they journey through vibrant text-based encounters, players make choices that affect relationships and alliances, leading to numerous endings filled with humor and unexpected twists. The game combines clever wordplay with tense decisions, daring heists, and endless heart-themed riddles as Cass attempts to find out whose heart is really theirs.
