I absolutely loved this idea and had to test the map, I don't think I've seen anybody try something like this on fh before.
Just some feedback, since I don't know how much of the story you did, but the cave route is inaccessible for me. Also a texture on the candyvan door was missing, but that could just be my game being weird. This was great fun though, and the text and objects moved to face the camera perfectly. I hope you'll continue this, it was so good :^)
