In 'Whose Hellos Are These, Anyway?', players step into the shoes of a disillusioned perfumer named Echo, who wakes up in a vibrant but bizarre world renowned for its unique greetings. Here, each hello has a distinct scent, and the interactions between the inhabitants are dictated by the fragrances they carry. However, something sinister is at play; some hellos have gone rogue, causing chaos and confusion among the citizens. Players must traverse this eccentric realm, solve humorous and dramatic scent-based puzzles, and uncover the source of the rogue hellos before the world is plunged into an olfactory meltdown. Along the way, Echo will encounter quirky characters, including a cynical greeting ghost who provides ironic commentary, and a pompous perfume critic with an inflated ego, adding layers of humor and eccentricity to the adventure.
