Sym is a puzzle-platformer video game that explores social anxiety disorder. Players take on the role of Josh, a teenage boy who has created an alternate world to escape from his fears and anxieties. The game follows Josh as he navigates two contrasting worlds - one representing his perception of reality, and the other being the world he built for himself to avoid fear. Players must help Josh reconcile these two different realms by solving puzzles in order to progress through each level.
