I love this cute game :) I created an Itch.io account just to comment here (as others have). Looks like you have big plans for it, good luck developing!
I wanted to point out a potential problem with the game: your "workers" count does not go into negative. This means that if you assign all of your workers to jobs (such as lumber or mining), you can now destroy their homes and they'll still do their jobs (which is beneficial because it lowers your population, so you don't have to pay food for those people anymore, and you can now use that land for something else).
If you have a very high food cost for the night and no food to pay for it, your happiness will go down until you get game over. But then on the game over screen, the happiness will start to go back up as you're still being charged for the food in the background, and it can even go way over 100% (does this suggest that the afterlife will make us happier than we can imagine? just kidding hahaha).
I think it's fun to surround a windmill with farms and then destroy the windmill. It's like setting off a bomb hahaha.
I would suggest a way to get rid of water tiles. Perhaps a fishing dock. And I would suggest that when you're hovered over the square behind a tall structure (such as an archery tower), that it would make that building invisible (or an outline) so you can see what is behind it.
