In a post-apocalyptic world where communication has devolved to nothing but greetings and salutations, you play as Tessa, a rogue linguist. Your mission is to uncover the source of a mysterious greeting that is spreading across remnants of society, leading people to bizarre behaviors. Explore eccentric characters, decipher problematic etiquette, and solve the ultimate mystery: who is behind these hellos? Engage in whimsical conversations, gather clues, and choose your responses carefully to reveal hidden layers of humor and absurdity. Your choices shape the reactions of colorful characters, from a paranoid greeting cult to a grumpy scientist obsessed with punctuation.
