You have an Options screen with Audio and Music, but neither seem to do anything. Also why is there Audio separate from Music? Is Audio supposed to be for Sound FX? If they aren't active in the current version, it would be good to hide them for now.
In the tutorial, it says "add some archers to you army", instead of "your" army".
On the second turn of the tutorial it says to take the next region on your own. I clicked on the army, and tried to click on Army Actions, but nothing happened. I don't know if that is because of the tutorial, or because there is nothing to do in the current region. It would be good to give the player some feedback here, possibly greying out the button if it can't be used.
I found the font could be hard to read in places, such as the pop ups used in the tutorial. I know it can be hard to find a good font, and font size, to fit everything on screen when you have a lot to say. Some of the text felt a bit blurry, probably from scaling. It might help if you could increase the contrast a bit by slightly darkening the background.
I played a bit on the Demo Map. It feels like a good strategy game. There are lots of little things to manage and monitor. The tutorial gave a good overview of the basics of how to play, allowing the player to get in and not be overwhelmed. There is still plenty to learn by playing.
