Set in a quirky 1980s suburban neighborhood, players assume the role of an amateur detective who stumbles upon an outrageous and inexplicable phenomenon: greeting cards mysteriously appearing on doorsteps, all signed by a secretive figure known only as 'The Hellos'. Each card contains a riddle or bizarre phrase that hints at the secrets of the card recipients—neighbors with eccentric personalities and hidden stories. As players explore the neighborhood, they interact with colorful characters, piece together clues from the cards, and uncover a tangled web of humorous secrets. The game blends mystery with comedy, where players must solve each card's riddle while building quirky relationships with their zany neighbors, leading to an unexpected twist by the end.
