The game looks nice and I really enjoyed the upgrade mechanic! Also props for making the sound effects with your mouth :D
But I have some questions: I understand that "space" is used to collect wood, but what does "e" do? Because I think I saw a hint to press "e", but I didn't see something happening.
And then I accidentally built a fence, but I didn't see the point in that so it kind of felt like I was wasting wood. Is there a point to building the fences?
