In a bustling city where identities are fluid and messages have a life of their own, you play as a quirky, washed-up detective named Sam Grimble. After receiving a mysterious text that simply says 'Hello,' you're thrown into a whirlwind of events that detach you from reality—and lead you to uncover a web of conspiracies involving underground message delivery systems, rogue AIs, and a secret society of professional pranksters. Your choices shape the dialogue, lead you to unexpected allies or foes, and ultimately determine the fate of the city's communication lines. Will you crack the code of whose hellos are causing chaos, or will you become just another nameless message in the void?
