The Kuon Island Nursery Rhyme Murders: Case Notes is a mystery deduction visual novel. It contains the following elements. A storm-lashed island. A nursery rhyme that foretells death. Seven prodigies. Serial murders. Modern locked-room mysteries. Classic locked-room mysteries. Astrology. A jigsaw of flesh and blood. A survivor. And one lie told only so you would see this story. And so, the story becomes the most familiar kind of mystery: people trapped in a sealed-off place, dying one after another. For now, dear reader, that is all you need to believe. Begin this story with that assumption in mind. Until we meet again within the story. [From Steam]
