It should be a little bit easier to find your way around, because everything looks the same. Furthermore, it's always a little odd that the fog of war is trees or ocean when it could be black boxes, and it only appears down and right for me.

I tried to craft a club and the game crashed

I think it's a solid idea and it's functional but if the gameplay is just left clicking I wish you could simply hold down tab to attack the closest target, get the closest item or cut the closest tree.

Also pressing the craft button without selecting an item crashes the game but it was otherwise stable for me.

Hope to see more of this in future DDs!
