MasterGame is an extremely unique Medium Demon level created by Serponge. It plays as a long RPG game, using passwords to save your progress, and continue from where you left off on another attempt. Although it is technically only 6 minutes in length, it could be considered to longest rated level due to the multiple attempts required to complete it. Unfortunately, some players aquire passwords to later parts of the level from other players in order to skip parts and complete it much faster. This, however cannot be helped.
