Comastuck is the most difficult adventure ever created. It follows the misadventures of an unnamed protagonist trapped within the nothingness of his own brain.
Comastuck spawned out of the thread "Homestuck, RE: the Title," mostly independently of the designs of the writer and suggesters. It follows an unnamed protagonist who lies in a vegetative state, feebly trying to escape. Throughout the few pages of the adventure, he tries and fails to imagine something that might give him hope. A few pages in, all participating surrendered, laughing it off as a "joke." Though listed as Completed, Comastuck was never beaten on the forum; however, Leaf claims to have won after a year of nonstop play.
