The Kid is zapped into a parallel universe and immediately meets Everett — an eccentric, sarcastic scientist who has built a device for shifting between dimensions and has been using it without much supervision. The two discover they share a dangerous mutual curiosity about what lies across the multiverse, and set off together to a strange island that holds key answers about Everett's past. Old acquaintances with dubious intentions are already hunting them. What Lies in the Multiverse is a 2D puzzle-platformer built around the chaos that follows.
