Not your normal Mario64 gameplay.
According to a report from Nintendo Life, a project called "Another Princess is in Our Castle" is currently in the works and essentially turns Super Mario 64 into a horror game. A video uploaded to YouTube gives a brief overview of what players can expect. Played from a first-person perspective, Mario can be seen wandering around the castle, lantern in hand. At one point, a ghostly Princess Peach bursts through the door, eventually killing the player. A retry shows that there is a chest in the room that Mario can hide in when the spectral princess arrives.
