Back Door

The Back Door is a level in the Valley of Bowser in Super Mario World that is accessed by completing Valley Fortress. It is similar to the Front Door of Bowser's Castle but skips over the majority of the level, starting in the dark room. The only difference in this room from the Front Door path is the inclusion of a Midway Gate just before the fight to Bowser. The battle with Bowser is unchanged, as are the credits and ending scenes. Because the game cannot be saved after completing the level (in the SNES version), it does not count toward 100% completion.

Notes[edit ]

• The game's bright palette in the remake makes it so that the red ? block light is less necessary for the last part of the level, especially on devices with a bright backlit screen.
• In Super Mario World: Super Mario Advance 2, even after the player defeats Bowser, it is impossible to leave the Back Door without quitting the game or losing a life.
• A reference to this level was made in New Super Mario Bros. Wii . By taking a secret exit from the World 7 tower and finishing the secret level, it is possible to go through a secret entry to the World 7 castle, skipping almost the whole level, except for the final Sledge Bro and the door to Ludwig von Koopa.
  • A similar reference is made in New Super Mario Bros. U (and New Super Luigi U ), where the player can take a shortcut (and the final Star Coin) in Roy's Conveyor Castle/Roy's Ironclad Castle by using red switch blocks to get behind the castle.
