I as a duck watch a lot of Game Theorist. And including The Fnaf ones I find it interesting.

There is a lot of characters and something called remnant that is a soul of something like a dog or a person. There is a animatronic called spring trap that is kind of fused with William Afton (A.k.a. The Purple man) that is a killer.

He killed a girl named “Cassidy” that is the face of the custom night game and Cassidy is golden Freddy and the game over face from the custom night game. And I think there will be more games.
