Hey,
This sounds interesting both as a programmer and a FNAF fan. I have experience with Unity, as well as Godot, although I’m more comfortable with Unity overall. Seeing as you have the gameplay loop already fleshed out, it shouldn’t be difficult to bring your game to life.
I can only really contribute to the programming side though, any of the art and sound design would have to be someone else.
