By the way, the jump scare comes when you get to 98% power (the orange thing at the top that writes "Power:" next to it). The name of this project is based off of a game called Five Nights At Freddy's (FNAF). Also, this project isn't similar to the real FNAF games, but the building is. By the way, there is a headphone warning, and if you aren't using a headphone, then don't have your volume to the max.
