Luigi wins a mansion in a contest and his brother, Mario, goes missing there. It is your goal to search the haunted mansion to figure out where he is. Your weapons to protect you are a flashlight and the Poltergust 3000, a ghost vacuum. Capturing ghosts and collecting keys helps you progress in your quest to find Mario.

NEVERDOORS follows the same general route as the previous movie, but improves times for every room, and saves a whopping ~20 seconds by incorporating a recently-discovered trick for defeating King Boo in one cycle instead of two. The submission notes contain much more detail about the myriad techniques that were used to create this TAS.

This run plays the Hidden Mansion, a mode unlocked after beating the game once that increases the power of the Poltergust and allows skipping some cutscenes, to make the run more entertaining. We do not normally accept runs that start from dirty SRAM; see the rules for more details.
