The Darkness

The Darkness is a secret world that the player may not encounter in most runs. The only way to access it is by killing 3 Friendly Droids that spawn in a special room. This will cause the message "Wrath takes hold." to appear, and the next world will be replaced by the Darkness.

All enemies that spawn here are world-exclusive to the Darkness, although The Shadow may be seen in other worlds through random buttons.

Environment
The Darkness takes place at night. It has black granite walls and grey floors. Other than that, it is featureless.

Trivia

 * The Darkness is one of three worlds that disables the Control ability. If used, a flavour text will pop up saying "You cannot Escape."
 * The only world whose time can't be turned to day. Trying to do so will have flavour text pop up saying "It's too dark."
 * It is possible to skip the boss fight by using a Skipping Stone.
