In 'Whose Hellos Are These, Anyway?', players take on the role of a quirky linguist named Lex, who uncovers a bizarre mystery in a small town where residents have begun receiving mysterious messages in various languages—each starting with an unfamiliar 'hello.' As Lex investigates, the player must navigate through a web of eccentric characters, solve language puzzles, and decode the secrets behind the greetings, all while racing against time and dealing with a rival cryptologist determined to claim the mystery for himself. Choices matter as players can ally with townsfolk or thwart their plans, leading to multiple endings and unexpected twists.
