Trivia

• The Dark Room is the only floor in the game which originates from Rebirth. All the other floors included in Rebirth at its launch were from the original flash game and its dlc Wrath of the Lamb.
• The Dark Room is also the name of a room which, like its name suggests, is plunged into complete darkness, for the notable purpose of processing photos. The fact access to this floor is done by touching the chest in Sheol while holding The NegativeIf the character has half a red heart or no red hearts after taking damage, it triggers The Necronomicon effect, damaging all enemies in the room. Also allows entrance into the Dark Room., which is the name given to a photo which has not been processed yet and whose colours and hues are inverted, might be a nod to this.
• The layout to the Chest and to the Dark Room are identical for a given seed.
• One of the super secret room layouts is of the Dark Room and a black heart. The sprite for the door is a portal rather than a gray door, however, due to the fact that bombed-out entrances in the Dark Room appear as portals.
  • This secret room appears floating in a black void on most floors, but in the Dark Room it appears in a purple misty void instead, just like all the other rooms.

Music

The music for the Dark Room is titled Devoid, which means “empty”.
