I also started to suspect that Mangle and Funtime Foxy were different after the trailer, before you even mentioned it. Mangle could've been some sort of remake. Also, it could take place in the future, or around FNAF 3, soon before or after. Also, the footage where you move looks like freeroam(not the vents, but the two clips before that).
