Nice little strategy game. Love the beautiful CGA work. Beat the game on easy on my first try, but I think I kind of got lucky with empty plains and having a big city very close to the invasion point. Haven't tried the other difficulty levels yet.
Back in the Civ1 days I always loved the cozy start of game when you managed 1 or 2 cities and spent most of your time exploring, but managing a whole empire in the later stages always felt like too much for me. So, I did feel a bit overwhelmed with having a whole lot of cities and resources right at the start (+ the 36 page manual), but luckily there wasn't much micromanagement involved and it was pretty straightforward and smooth to play. A great jam entry!
