In a quirky, dimension-hopping adventure, players take on the role of Cass, a confused time-traveler embroiled in a mix-up of greetings. Each stop in various timelines and alternate realities forces Cass to decipher which 'hello' belongs to which universe. From a gangster-ridden 1920s New York to a futuristic society where greetings are lethal weapons, every encounter is a hilarious puzzle. Players must navigate conversations, build friendships, and uncover secrets to solve the mystery of duplicating hellos, learning that sometimes a simple greeting can be the key to saving, or doom, an entire reality.
