In 'Greetings from the Multiverse: Who Dis?', players take on the role of a disgruntled interdimensional postman tasked with delivering mail across bizarre alternate realities. Each universe you visit presents its own unique challenges, from navigating a world where everything is made of candy to dealing with sentient technology that communicates only in riddles. With a quirky cast of characters — including a time-traveling dinosaur and a wisecracking robot — players must solve environmental puzzles, engage in comical banter, and dodge reality-warping dangers. The goal? Deliver your packages and possibly uncover a cosmic conspiracy about the nature of the multiverse itself, all while maintaining your sanity and sense of humor.
