In 'Worlds Unbound: Whose Hello is it Anyway?', players assume the role of a world-weary interdimensional postal worker named Jax, whose job is to deliver greetings across a chaotic multiverse. Each delivery leads Jax into bizarre realities filled with eccentric inhabitants, from sentient puns to existential dread. As Jax navigates through these odd dimensions, he must solve quirky puzzles, manage the conflicting whims of bizarre characters, and piece together the mystery of an impending miscommunication catastrophe that threatens the very fabric of reality. All the while, players indulge in humorous dialogues where choices define their relationships with the worlds they visit and how their deliveries impact the cosmic humor of the universe.
