OK Pineconn, I am taking your suggestion and trying Land of Serenity again. Having fun, am now looking for level 4, seems there is a maze north in the dessert I haven't figured out. Is there a clue somewhere?
Land of Serenity
Level 4 is in the far southwest corner of the main Overworld, in the "Cemetery" area (brown forest with gravestones) with invisible enemies.
There's an old man in a cave that offers information for rupees in the regular Overworld. I forget exactly where unfortunately. But pay him 100 rupees and he'll give you the solution to the maze that I think you're at.
