Set in a surreal, dimension-hopping world where the boundaries of reality are thin, players take on the role of an enigmatic character who must navigate through a bizarre series of social puzzles. Each realm they enter presents absurd situations, strange characters, and humorous exchanges that challenge their ability to discern 'whose hello it is' and what it means. As players explore each dimension, they'll have to solve mysteries connected to the identity of individuals they meet, and often, these mysteries are intricately tied to the comedic and chaotic nature of each realm. The choices they make will affect not just their interactions, but also the fabric of the realities they traverse.
