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 improves their previous movie by 35.3 seconds, thanks to a much improved Chauncey fight, being able to be defeated in one cycle. Please read the author's comments for more details.

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.
