First off, I loved the game, but there were a couple puzzles that I sort of had to brute force, or had errors in them:

* The 6 arrows on the start space should be pointing left, not right, since you are presumably going from L to D to spell "HOLD".  Going 6 spaces to the right of L would go off the keyboard.

* I had to brute force finding the path in the sea in the south-east corner of the map.  I assumed by the "sandy dunes" clue that it would be some sort of sand mass jutting out into the water, but there are a lot of those on the map, so it was trial-and-error finding the right one

* I ended up brute forcing the order of the keepers for the final puzzle, but in retrospect was this the logic you were supposed to use: The order of the colors in "VAPORESIN" when examined went Blue, Purple, Rainbow, Yellow, Green.  The rainbow letter was R, which could also represent Red.  The order you need to visit the keepers in is therefore Blue, Red, Green?
