I loved this game, especially the aspect of navigating with a map :)
I did got stuck though, didn't recall (or saw) the target island after bringing the gem to the start... I'll be giving this game another go, later today.
I did noticed there weren't any background music in-game, only at the menu. And, the game didn't go to fullscreen & the text were a little too small to read.
The map is always a bonus on such a game, but I'd love to have the ability to pan around the map & plan out my journey...
