In 'Whose Hello?', players take on the role of an amateur detective named Sam Quirk, who inadvertently receives a mysterious message that simply says 'Hello?' from a series of increasingly bizarre characters. As Sam unravels the curious connections between these individuals—a conspiracy theorist, an eccentric artist, a talking cat, and a disgruntled ghost—players must navigate through witty dialogue, clever puzzles, and unexpected twists. Each interaction leads to more questions, and with limited time to solve the mystery before it triggers a whimsical disaster, players need to piece together clues and determine whose 'Hello?' holds the key to unraveling a grand scheme that could change their mundane town forever.
