8-Bit Overworld was the former overworld for FNaF World.
This is the former overworld in FNaF World. It formerly replaced the 3D Overworld. However, it contains all the locations. It is unknown as of now if it will be in the rereleased in the free version on GameJolt as it only has the demo on it, but because they will use the 3D Overworld in it. The mobile version does not have the 2-D version.
