Alright, I will explain the new mechanics and other stuff. First things first I will tell you some new things I MAY add!
NEW STUFF
-New Office (or survival room so to say)
-Zap Flash used to lure “them” away, press ALT to use
-Voice Acting (Only for a “phone-guy” and random quotes being said by some characters.)
-New Location
-New Characters
-New “Incidents”
-New Story
-Simon Says mechanic thing used to fend off one character
-A Phantom BB spin-off
-Extras
-Hidden Codes
-Minigames that were never commonly seen in FNaF games.
-5 Normal Nights
-5 Bonus Nights
-Easter Eggs
-16-bit minigames
-Cutscenes
-Custom Night (Hopefully)
-Pills used to lower your heart-rate
-Loud Sounds
-Intense Ambiance
-Flashing Lights
-And lots of jumpscares!

I can’t guarantee all of this will be in the game but let’s hope!
