Thanks for your kind words. I will definitely make the improvements people have suggested. I'd also quite like to take it further if there is an audience for it, maybe making a small campaign (as have had a few good ideas on that). My world is chunked so I could make a much larger island / islands and make a much slower build up to the game.
Hey glad it has inspired you for a game, that's always a great compliment in itself. Hope it works out for you and you will have to let me play it when you are done!
