Salavage, fix, and clean any animatronic that you can find. But don't fail. They are watching you from the shadows

After the opening of sister location, the fnaf 2 location was left to rot. You, a hazard cleaner, are hired to salavage, fix, and clean any left over animatronics. When you are cleaning, there is cries of children, but you're all alone.

anyone have a good engine (On the free side or cheap side) to make a good FNAF fan game?
