Clue room: Move to the south-east corner of the map, then walk
north one screen, walk west one screen, and enter the trees at
the first bend in the "tree path". Follow the path that
leads to the middle of the west edge, walk one screen west, and
continue forward on this hidden path to enter the Nunnery. The
"God of Kukulcan" will then reveal a puzzle clue.
