Don't worry, the play and credits button actually work lol.
I am a total beginner Scratcher, so I had to get an idea for what to do with this from CandyIsHere on Youtube or @CandyService on Scratch. Other than the main menu, which I did the Candy's tutorial for, the game is 100% original. Of course, FNaF belongs to Scott Cawthon, and that's where I got the idea from.
