A very eye-catching thumbnail, title, and concept. What you have is well-executed, but what you have is mostly a game of keeping two numbers the same. A second resource, or town parameters (e.g. population, production, etc), world events, or... a third town... would expand this game's horizons so much further. It's also difficult to know when, and why, food production occurs. From a player's perspective, it's purely random; and is mostly a game of reflexes. Some caravans rolling in, or farms growing and being harvested would help, maybe even playing with the seasons.
The concept makes my brain work, and that's a good thing. It just needs some time to develop, I did see that you were only able to spend 8 hours on it.
