FNAF The Killer in Purple

Game description:

Who is the Killer in Purple? You may have not met this character in FNAF games, but his shadow is actually looming over all the grim events happening in every chapter. This mysterious and vile man dressed in a violet suit is actually the creator of animatronics! No wonder they share the murderous nature of the person who made them. In this game, you will be running away not only from Freddie and other dolls, but also from William Afton. He is way smarter than his creations, so he won't leave you alone and fall for your diversionary tactics so easily. Good luck!
