Whose Hellos Are These, Anyway?

In a quirky, darkly comedic world where greetings hold mysterious powers, you play as Billie, an undercover social investigator tasked with uncovering the truth behind the bizarre phenomenon of people losing their acknowledgement skills. One day, people in your town start mysteriously saying 'hello' to strangers—hellos that seem to carry ominous vibes. As you navigate the town's peculiar denizens, you must choose how to interact with them, solving riddles and gathering clues to unravel the strange affliction while also trying to maintain your own sanity. Your choices will alter the story's course, leading to multiple endings based on how effectively you investigate the mystery and whether you can keep your ‘hellos’ (and possibly yourself) intact.
