This mode SUUUUCKS and is frustrating because the first 4 hours of the night are basically completely free as long as you have functioning ears. No matter when Foxy enters your room, it's simple enough to work him into your cycle (send him back immediately and then continue whatever you were doing before, from then on, check on him after every time you get rid of the Freddles). The real issue for me is that Nightmare is very frustrating, not just with his fake laughs, but also with how strict the timer can sometimes be, combined with the audio cues being a little muddied by your own footsteps. Also doesn't help that this feels obscenely tense and scary to me no matter how much I play, it's inherently stressful to me x_x
