I'd like to preface this by saying I was playing on browser.
This game is really good, except for a few things: firstly, food didn't seem to do anything aside from be used for quests. Secondly, the game froze before battles, or when I tried to make a new campaign not in the first option. Thirdly, whenever I upgraded units, they didn't keep the upgrades if I reopened the upgrade tab. This aforementioned upgrade tab took me two hours to find. Finally, the villages don't produce any of the materials required for the late game, e.g. iron ingots, ale, axes, etc. The villages that could produce these always seem to have the workers assigned as idle.
But aside from that, this game is great. Nice graphics, good animations, satisfying battles, you have the groundwork for a great game, and the issues I experienced might just be a browser thing. Good job. 9/10. ;D
