Thank you for the feedback and for giving it a try!
It's not really the kind of game I play either, but I wanted to try making something different from what I normally make.
- The yellow outline around a tile shows when it is ready to be harvested (With right click),
could have made that more clear to the user, I will add it to the description for now.
- You can sell your initial trees, but I don't know if you can win by doing that or not.
