In the video, a lady explains the rules of this game, which will disturb everyone in your building waiting for the elevator, even if you don't visit another dimension.
You take an elevator at least 10 stories up and punch buttons out of sequence to activate the game's darker parts.
Supposedly, a lady in a hat will ask you whether it works.
This woman is reportedly unnatural, and if you speak to her, she'll murder you or take you into her demon realm, however how people would know this is unknown.
Explore if you dare, or remain in the elevator to be hounded by demon ladies while you push buttons in the same order as before, hoping to reach your home planet or at least avoid security.
This current version on "Bloody Mary" is for someone else. Taking the stairs.
