Back Door: Difference between revisions

A reference to this level was made in ''[[New Super Mario Bros. Wii]]''. By taking a secret exit from the [[World 7 (New Super Mario Bros. Wii)|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 as such, ''[[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 Block]]s to get behind the castle.

*In the [[Game Boy Advance]] remake of ''[[Super Mario World]]'', even if the player defeats [[Bowser]], it is impossible to exit this level without quitting the game.

*If ''Super Mario Advance 2: Super Mario World'' is played on a backlit Nintendo handheld (such as a [[Game Boy Advance SP]] or [[Nintendo DS Lite]]), the background in the dark section of the level will be so bright that the red ? block light is actually not needed to complete the level. This is because those systems are backlit and this game was intended to be played on a non-backlit Game Boy Advance.
