In a bustling steampunk metropolis, players assume the role of a heart-harvesting detective who delves into the web of love and betrayal among the elite. Only by exploring the emotional undercurrents and uncovering hidden motives can they solve heart-related murders that disrupt the city's chaotic harmony. Choices shape relationships with a cast of eccentric characters, leading to multiple endings based on how much love (or heart) you choose to give or take. Puzzles and moral dilemmas challenge players to weigh the value of emotions versus duty.
