Fanmade glitch variant: Figure

Name: F. Gimmick: after collecting a glitch fragment in a room with figure in, a F spawns in and resets the room. They are wildly faster, and their minigame is moving and glitching. They are less visible the further away you are, move slightly and much quieter as your further away, attempting to sneak attack you if they know where you are. Only pick up the fragment if you KNOW you can overcome them. In room 50 once you pick up the fragment, the room resets and the cutscene plays, this time with F in it. Same goes for room 100, and even the ending cutscene will have changed once you beat it. In any of the cave rooms, the room resets and the next 3 rooms are figure rooms with F in them.
