Fnaf makes me go crazy...

Shoutout to all the fnaf fans!!! Have you ever played Fnaf's Pizzeria simulator? Well, I did.
Night 4 is a nightmare. I think I'm playing the right way but eventually some animatronic (yes Afton I'm talking about YOU) kills me and I just can't go on.
Anyways I might just suck at playing, but anyways I love the game and all the other games of Scott...
Any tips??
