All you have to do is survive the night. Click the vent to seal or unseal it. If sealed it takes air. Dont use on Night 1. Click the power generator too get power you cannot generate power when the door is closed or when the lights on. Comment if you don't get it or if there is any bugs. Ctrl for flashlight or Space for Vent light Click the fan to turn it off and on.
