Ok so basically I've never seen FNAF 6 gameplay so I don't know how this is actually supposed to work??? So, I made my own system. PREPARE FOR READING When the game starts (you click the flag), the Patience Meter will rapidly go down. You have to click the button at the bottom of the screen to pull up your paper and refill it. You then have to wait 1.5 seconds before you can put it down again. Keep it up for too long and Lefty will begin to move. If he does move, press Z to zap him and put him back in place. If you don't he could get too close and... Anyways, this will deplete his value by 100. If his value is ever less than 100, well... Anyways survive for 1400 seconds. Oh, and another thing I forgot to mention, you can't zap him while looking at the paper.
