In 'Who Left This Here?', players assume the role of an amateur detective named Riley Quinn. During a quiet lunch break at a popular cafe, a mysterious package appears at your table, and the cafe plunges into chaos as patrons speculate its origin. Instead of escaping or searching an island, you dive into the lives of the cafe's eclectic customers while figuring out who left the strange package and why. Each character has their own secrets, motivations, and alibis. With choices that can lead to dead ends or vital clues, players navigate through a web of humor, drama, and unforeseen twists, making every decision count to unravel the mystery before time runs out.
