These are the reasons.

• The gameplay is somewhat POORLY done, according to users, including myself.

• The reason it's a bit controversial is because the images and sounds are taken from the Jolly saga, Dormitabis, Granny, the DSMIS saga, ToyStory3.EXE, Hello Neighbor, Sister Location, etc.

• English spelling problems, as I'm going to explain here; I didn't know English before and used random letters or words that weren't understood at all, which caused the game to be criticized even more.

• There are things that don't make sense.

• Cinematics that weren't cinematics; they were just images, which were apparently more confusing than you'd imagine.

• The death of the purple man had nothing to do with the game, since in my opinion, William Afton belongs to FNAF, not this one.

HOW COULD I BE SO IDIOT TO DO THESE THINGS? I'M A CRAPPY PERSON ;(
