In 'Whose Hello?', players step into the quirky shoes of Sam, a professional greeting card detective in a whimsical, cartoonish world. After a series of bizarre and chaotic events, every citizen’s greeting has been swapped, leading to confusion and hilarity. As Sam, you must navigate through various eccentric neighborhoods, interrogate colorful characters, and piece together clues from nonsensical conversations. Solve the mystery of 'Whose Hello?' by uncovering the secret behind the Greeting Card Conspiracy—a plot to take over the city's social interactions through wrongly delivered hellos. Players will choose dialogue options that can either lead to comedy gold or total chaos, impacting the outcome of each interaction and the resolution of the mystery.
