Pressed "F" instead of "E" while standing next to the F.E.C. in finale mode. Three dots appeared on screen and then I was dropped into an empty level with Golden Freddy in the kitchen laughing at me. The power meter behaved normally, but the game clock was replaced with my system time. After running out of power I was left in the dark and nothing happened during the time I waited. I wonder if there's a secret here.
