Five Nights At Freddy’s 4

The game is a prequel to the original FNAF and consists of several mini-games. The action takes place in the 80s and its events relate to the appearance of those crazy things that then led to the revival of animatronic figures. In the game, you need to solve various puzzles to get out of the room and progress through the story. Each level has its own riddles. Here you can find many references to the previous parts, if you are very careful.
