Click the two red buttons to close the doors. Click the fan to turn it off (Note: the fan is cosmetic). When you see monsters or hear noises, close the appropriate door. There is some learning to go into this, like what creature goes to what door. The locked game mode is unlocked after completing the night, and the code it tells you can be used to unlock custom night through the “LOAD” button.
Thanks to Scott Cawthon for giving me the idea (kinda) and making Five Nights at Freddy’s. I know, the art sucks. You don’t have to comment about it. @sus
