Like the main game play of fnaf 1 with the two doors and stuff, I would say the puppet winding from fnaf two that that hella sucks so the flash light and hallway of fnaf two, the movement of fnaf 4, like you have to turn behind and shit wait for breathing then flash them down if their fair and hide when their close.

With your shit being able to broke down and you have to repair them with repair pad thing from fnaf 3, like imagine you close your door too much and now it’s stuck closed so it wasting slightly more power from it trying to open again.

And you needing to do task to complete the job like in 6
