There are 9,223,372,036,854,775,807 levels of the Backrooms. Each one is unique and very hard to escape from. Each level has unique monsters that will try to kill you. The first level is the one that the player starts in. It is an office space that extends for miles. Once the player escapes from level one, you can improvise any new levels you want until the player reaches level 9,223,372,036,854,775,807 and escapes back to Earth.
