Played this in a group of three. We found some of the clues to be quite obscure - certainly, if I hadn't read some of your comments on the forum I think we would've given up earlier (wait, caw caw).

There's a secret passage to the east which links back to the beach. It doesn't seem to do anything. Meeting the butterfly and following the passage in circles was about where we finished.
