Ok so stalling foxy is key. I beat 4/20 With 7% left. foxy came only twise and got lucky with door dudes. What i did was close the door 2.5 sec after the last footstep and go to cams immediately. Wait 2 sec, go open the door and open cams again. (This will stall foxy alot. repeat until 5am). Just close right door when freddy boutta kill u. if you get to 5am and have succesfully dealt with freddy, just go to cams and stall foxy as much as possible to hopefully prevent the third run. quick note dont use lights and restart if foxy comes before it hits 1am. Hope this helps <3.
