Null

Null is a short, one-room World that is currently accessed after the Atomic Factory. Inside it lies a single red button that marks your run as a win when clicked. You can't click this button until Null's opening text slides away.

Environment
Null has a blackish purple color scheme, with granite walls and floor. This world will take place at night, but can be set to day if the player has Lantern or the Illumina.

In the middle of the room, there is a spinning Rune with an elevated button. This button will end your run and give you a win and points.

Trivia

 * This is currently as of now, the last world.
 * Null's position as a world is still argued over.
 * You can warp forward to null in the Mechtropolis special room, which is glorified as a world skip.
