Playing the game and noticed a couple of things: are the axe and pickaxe mixed? Because I crafted a pickaxe and it seemed to damage only treesstill, I like the premise!
That was happening but i fixed it before release, however i may have accidentally sent an older version to my friend when he updated it(I couldn't access my computer on the last day and the game needed a few changes)
Actually after a quick test it doesn't seem like this issue is in the HTML version, did you download it?
I tried the HTML version, but maybe I did something wrong when playing it and got confused
