The artstyle is really cute!
I do like the concept of the game, but I don't think it really came together. A problem is that the game is a bit too lumber-y. Every building requires lumber to build, every soldier/archer requires lumber to hire, packing your buildings into caravans requires lumber, and buying new land requires lumber. Because of that, you're constantly running back to your lumber mills to do everything, which isn't as true for the mines/windmills.
It's also really easy to screw yourself out of resources. Like I packed everything up to head to the next area, only to find that I was 5 lumber short, which meant I had to put my lumbermill BACK and get more lumber before the tile disappeared. It's a bit unforgiving.
Also, please update the controls on your itch page to include all the controls. It's really hard to tell the difference between "Press E to build" and "Press F to buy" when zoomed out, and while you can zoom in you don't really want to be doing that all the time.
Regardless, very creative idea!
