This is a quick project I made in my spare time. This minigame is not canon to FNaF or POPGOES to every detail, but it roughly follows the POPGOES story. Note that some doors will lock behind you, and that is not a glitch. Don't look back. However, there is a glitch whereas when you finish the minigame, you cannot return to the beginning screen, and the game therefore becomes unplayable. So it could be said that the game is playable only once, unless you refresh.
I credit Kane Carter for POPGOES, and Scott Cawthon for the Five Nights at Freddy's franchise.
