Five Nights At Freddy's One is a game built and made by Scott Cawthon alone. He found incouragement from an insult on one of his other games. "The characters look like scary animatronics," one player replied on a comments space. Scott decided to use people's fears of Dolls moving and dolls themselves, as will as the reportedly inspirational comment, and out came Five Nights At Freddy's.
The game is fairly easy; click the buttons Light and Door for Lighting or shutting the door. Move your mouse down to the grey/white bar to pick up the monitor to the camera. The trick is, you have to conserve power to survive 6 hours, from 12 AM to 6. This wouldn't be hard, except there are two to six animatronics after you every night.
