On cams look only at foxy, look at her for 3-4 sec, then 5-6 sec break and repeat. You just need to pray the she will come to your office max 3 times xd And for freddy, timer on your phone will be useful. Just start when you start the night, and on 7:38 close right door, after few seconds she will laugh and you can open door. And for end you need good rng, beacuse you will lose your power before 6am for sure, so freddy must spend some time on playing her music and coming to you xd
