Symon is a puzzle game that tells the story of a bedridden hospital patient who sorely misses his home and family. The only thing he can do is to sleep and dream, which leads him to a place inside his imagination that is populated by a cast of unusual characters to meet and run errands for.

Repeated playthroughs of Symon is advised, since players are usually presented with the opportunity to collect a different piece of our protagonist's personal effects after every fruitful visit to the dreamworld.
