Little guys civ/polytopia. Decent once you understand the rules, I finished one run-through on British Isles (I really love the real lilfe mapping).
I don't like the struggle of passing through your own villages, they give 0/0, so your armies just die trying. Felt a bit too punishing, and I could not upgrade village to city even when piling more people.
I enjoyed the powers of the villages though, the horses, boats etc. Definitely good potential for the idea, I bet quite a few would enjoy with just a bit more polish. Best of luck with the jam :D
