Thank you for this nice game! I ended on the second run with around 64 people. (~1h)
On the first run I didn't realized that you needed to harvest manually the farm (maybe because the other building are harvested automatically and that the apple tree doesn't need workers).
The possible improvements I could see would be: a button to restart (or go to main menu), information on farms and shipyard (and maybe on town hall, just to say the current food consumption), tower radius (to see the range).
