Hello there,
Just in case you didn't find the lighter, here's a little help......
Spoiler below, select the area to read the text It is in the donkey's pen on the island of Juturna. You need to feed him coconut popcorn for him to leave, then you can get it. See getting map piece 2
I hope you are enjoying the game so far. I made it so that you can not move to another area unless you have all the inventory needed. I hope that puts your mind at ease.
It is possible to get map pieces in any order though some of the puzzles will overlap each other. I tried to set it up so that the game wouldn't be completely linear in nature.
