Looks fun! Definitely interested to find out about the game. These browser games are getting really popular. I did one recently. Should be able to post a link to it at the end of April or May when it goes live.
Cool compass. Like the colours too. I'm not totally convinced by the coastline. It looks a bit too consistent in the pattern of the rough edge. Also, when you shrink this down I think you might lose that. Otherwise, coming along nicely.
