Hey! You're very welcome! Considering the effort you guys put into it, being a side-project along other things, makes the game and your work even more amazing and the minimum is to give proper recognition to that!
For the slave/citizen thing : exactly!! That's the purpose I had in mind when I wrote that. Like, some sort of extrema ratio when you lose everyone else and you need someone to build something, for example
About your feedback : I must agree with you, a food trickle alone without any other visual clue doesn't "fit" well with the gameplay. A quick solution to the problem could be a minus (-) value that appears together with the food resource counter when your troops start moving, to give a sense of the expenses. But at this point, I find that the effect on units HP more appealing, as it provides a sense of vulnerability to the units you send to the frontier. The problem is to find one easy way to make this effect reversible, so it doesn't affect the gameplay entirely, but just provide a small inconvenience to overcome in battle.
For the sake of brainstorming, maybe a visual clue could be a small "starving" symbol that appears with the unit thumbnail to show that they lost their "autonomy" and just need to come back to their territory to refreshen this countdown and avoid HP loss? It could be some "extrema ratio" that only appears after a very prolonged time "abroad," so affecting units HP during long sieges, stationary people outside the territory, or whatever action that takes longer that a definite time threshold so to not affect otherwise general movement of people?
Really, is definitely not an essential feature, tho. So I was just toying with the idea as long as it fits consistently with the overall game and makes sense to add. If it's too much of a burden, also coding-wise then nevermind
Slightly off-topic : since I discovered this forum and some amazing behind-the-scenes of the game, I stumbled across a concept idea that you proposed somewhere, about "settlements" that you can build elsewhere and develop independently as towns and cities alongside your capital and I just wanted to say that is a really great concept and intuition!! It would bring more focus on map features and strategic expansion and add another interesting flavor to the game.
Whatever the case, is really amazing all the improvements so far, so thank you and all the people involved for creating such a fun experience for everyone!
