Dont even know if anyones up to the point where im at. However, im trying to get into the room with the purple dot. I backtrack a bit, to a door with a chest behind it, and 4 windmills outside. Then the helper guy says how sophisicated it is and to look for other clues.
Been all over, and have been tryin to figure this out for atleast 3 hours. Need some serious help.
