Haven't noticed any bugs from not doing so, but click the flag twice just in case (or spam it like I do lol) Most instructions provided by phone guy (me) Press space bar in front of doors to close them Press space bar while on cams to close the vent Also forgot to mention in phone call, you have to close vents before red gets in your room. If you see him in the room then you can't do anything about it except pray that 6am comes before he attacks you.
