Great game especially for a first try!
I like how all the assets come together nicely.
Few improvement that I think might be good
1) Not sure how and where to start (Consider adding introductions or tutorials)
2) UI was not the most intuitive, took me some trying to realize what each buttons does (Consider adding words before the icons or tutorial will greatly benefit here)
3) Having to chop each tree individually, or attack each building individually.
4) I spend some time waiting for the goblins to attack but they never came at least for me. Not sure how long am I supposed to wait
Nevertheless, great job on completing the game and all the best! Cheers!
