Hi, I played your game and it keep my up :) I'm not played a lot and I have some thoughts that may be useful.
Personally, I would like to see the movement of enemy squads after they cross into the visible area. I'm not sure if the current implementation is part of a stealth or tactical mechanic.
I also think that instead of a modal screen explaining the losses, it might be better to show it through some kind of animation. A few times I was surprised that my cavalry was gone, and I didn’t understand why.
But once again, it could also be an interesting idea if the intention is that, as a general, I simply lose contact with some of my squads.
