If you have watched Markiplier's playthrough, then you might get the basic idea on how to beat it. On Night Three, Freddy comes out and tries to get to you, but remember, he hides in the shadows and can only see his sinister eyes. He comes on the right side and if you hear his laughter on that side, close the door quickly. You can hear the music playing in the kitchen. If you see Freddy staring very close at the camera, close the right door immediately. Keep checking it until he's away from the camera. Remember, the doors, lights, and camera take up energy, so most importantly, check on Foxy time to time while briefly checking the lights for Bonnie and Chica. The game plays by chance, so this is what I know.
