About the Fog of War: you are totally right.
At first I intended it to completely cover the map (as fow MUST do), but I thought it could confuse people on where to go.
Don't get me wrong: it is the purpose of fow, to explore the unknow and at the same time go cautiously... but since Island are floating, there is no connecting ground at the beginning, and you only see the sky, I wanted to give a little help.
Again, maybe I was just wrong making it easier and more casual... but it is still a Jam! :)
