IDEA!!!!! IF YOU COMPLETE THE GAME ON NORMAL MODE, THEN YOU UNLOCK A "LOW-POLY" MODE WHERE THE MODELS ARE ALL LOW POLY VERSIONS! Since Low-poly is creepy as hell
One of the things I wish that more of the fnaf games had were the hallucinations (I.G. the its me from fnaf 1, that one terrified me always) It's a mechanic I plan to impliment as the nights go on, the hallucinations become more frequent.
