Just monitor the cameras and use your flashlight to check the doors and the vent. If Goldie or Fishy are at one of your doors then close it, but if you don't then they'll get into your office and you have to put on the mask or they'll jump-scare you. If Trina is in your office put on the mask too, but if Tucker is in the vent keep your flashlight on him until he leaves.
Thanks to Scott Cawthon for making FNAF games so some credit goes to him.
