Previous one was quite hard actually. This one was simple but yet like you my friend was unable to solve it quickly. I liked her reaction when I showed her she just has to interact with two switches so decided to go with this combination.
tell me, after solving the riddle, should something happen right away? or do I need to go somewhere, etc., I just don't understand what to do next after solving it
Not sure if I understand correctly, but you do not need to banish the ghost. Just do the puzzle, end the hunt via computer in the van and you have the map available on the map select screen
