In a bustling, neon-lit metropolis, you play as a heartthief—a rogue with the unique ability to swap, trade, and manipulate hearts among the city's citizens. Each heart possesses memories and personality traits of its previous owner. Your mission is to navigate the pulsating underbelly of this city, helping or hindering individuals while confronting the societal chaos that ensues from your choices. As you trade hearts, you'll unravel stories of love, betrayal, and identity, all while an enigmatic overlord pulls the strings behind the scenes. The game challenges you not only to shift hearts but also to grapple with the moral implications of your actions, ultimately determining the fate of the metropolis and your own fragmented soul.
