Heartstrings: Who's Heart is it, Anyway?

In a world where emotions have been externalized into tangible, swapable 'heartstrings,' players take on the role of Sam, a hapless harpist who finds themselves tasked with orchestrating a grand concert to mend the hearts of the city's fractured relationships. Travel through different districts, each ruled by the emotional states of its citizens—from the Joyful Heights to the Gloomy Abyss—encounter quirky characters with specific heartstring troubles. Players must navigate choices that determine the fate of these relationships while uncovering a darker plot that threatens to cut the heartstrings of the city altogether. Can you strike a chord with their hearts, or will you end up playing a dirge of despair?
