Trivia[edit | edit source]

  • Stage 13 is the only non-standard stage that does not crash. It consists of 2x1 vertical rooms that have doors that only sometimes close, minimal enemies (usually 2 of the same type), and uses the Caves background. The music is a single layer of either the Blue Womb, the Cellar, or the Burning Basement music, and only plays when enemies are in the room. The boss is always The Duke of Flies, and no trapdoor or items spawn when the boss is defeated.
    • Stage 13a is the same, but with the Depths background. The boss is always Monstro II.
    • Stage 13b is the same, but with the Womb background. The boss is always The Duke of Flies.
    • Any variant beyond 13b is the same as stage 13.
    • The enemy spawn patterns are the same as the waves in Greed mode, suggesting that this stage is used to store the waves in the game.
  • Entering "stage 8" in Greed or Greedier mode will grant access to The Void. The rooms and music are same as The Void in regular mode, but the boss is Ultra Greed and will drop the Final Boss Chest. Entering the chest will play the final ending instead of End 18 or 19.
  • When using the "repeat" command, if the number given is larger than 10,000, the command will not work and a message saying "Don't get carried away" will show up.
