I have been keeping an eye on your project through 7DRL.org and it was one which called my attention the most over there. Congrats on your sucess
I have to say though that the game feels unpolished. I know, it' s a 7DRL but it feels half-baked at first impression. I've read the basic instructions and I don't know why I can't build farms near my city even though I have the gold (maybe it's due to the terrain?), for example, or how to interact with other cities or why I keep attacking those red things and nothing ever happens (the text say something like "Deals x damage to Sword")?? Getting killed by barbarians earlier on is common. Simply walking on the ocean tiles makes it feels like an alpha release or test build. Sometimes my @snake will just keep on walking on its own no matter what I try to do (it becomes mildly infuriating, the more your play).
I like the concept. In many ways it's similar to my own Javelin game (which is receiving a major update soon), which is part of why I was excited for it. Overall though it's hard to understand what's happening half of the time. Maybe with a little more work it could become pretty fun?
In special, it feels like I should be able to interact with cities somehow. I totally understand your design of having the stuff built outside the city (Javelin is exactly like that too, even more so in the next release). Wait a minute, I just realized you can see information by hovering the mouse - you should consider showing that on a popup too when space is clicked while in a city tile. Anyways, I still don't know how to build mobs or direct production at all. Is production only used to generating mobs via the barracks? What does food do?
On a plus note it works pretty well in the browser (responsive, loads fast, silences when changing tabs), etc!
There's definitely something wrong with the production system too, I've built a ton of cities, barracks (one per city), factories, farms and I still haven't seen a single pikemen come out of any of them. While I was doing the construction work I had it set to Mounted Knights and haven't seen one get produced in the 10 or 15 minutes while I was building everything else. I've changed all production to pikemen and have been walking around like a doofus and still no unit produced. Earlier on in this game I was able to produce plenty of scouts though.
OK so finally I went in and read the entire manual. Might be that the pikemen require iron (even though it says on the barracks menu that they require horses?) so I change all my barracks to spearmen instead. Still nothing, no matter how much I move around the map. Even if the issue was a lack of iron, the game should be informing me of this or at least grey out options that I cannot produce due to lack of resources in the area, I believe. The reason I didn't read the entire manual first is because I'm well acquainted to this sort of game and wanted to see how much I could work out on my own.

As I've said before, it feels more like an alpha build than anything ready to play, even though the concept is pretty neat for a "quick-and-dirty" TBS experience (compared to a full 4X game like Civilization).
EDIT running the game on Firefox, if that's useful.
