I like this! It's a lovely large world to walk through The puzzles are easy but they're not always obvious which makes for a nice change to the usual PuzzleScripts. I really like that you included a large map. It removed the frustration of wondering where to go next or where to find something I needed, so I could focus on how to achieve it.
I am still completely stumped as to how to reach the fifth mystic, but there's more to try...
Question with spoiler: Are you aware the raft can be stolen without paying for it by using the second raft?
