In 'Whose Hello?', players take on the role of an inconspicuous linguist who accidentally stumbles upon a mysterious greeting that can unlock time and space. Cornered by eccentric characters, each with their own idiosyncratic versions of 'hello', the player must engage in witty dialogue, solve humorous puzzles, and navigate bizarre worlds. Each choice alters the narrative, leading to delightful encounters with historical figures, mythical creatures, and even alternate versions of the protagonist. With every 'hello' they decipher, new realms of possibility open up, and the fate of communication hangs in the balance.
