Hey, thanks for reaching out. Yes, I do have a axe chopping animation. As for units carrying resources, I don't have any generic carry or specific carry animation for resources. Buildings have some tiles that make them look more worn down, but no serious damage tiles.
As for "enemies", it is mostly just animals/insects at the moment, or other humans. I do plan on adding other races to the series, like goblins, etc.
I have around 30 unique animal/insects (not counting baby variations). Oh, also a ghost "enemy" exists too.
With all that said, these ideas are all great additions that I will certainly be adding in the coming updates, thanks!
