Thanks, glad you love it! Good catch on the sea: right now the water works as an escape route, so pinned troops don’t get pocketed. I’ll look into letting the coast count for encirclements.
About towns: taking one with a single infantry is meant to be tough, since the town’s area cuts off a lone attacker. Bring a second unit or push your front line up to the town first, and it gets much easier. That said, I’ll take another look at how much area towns control. Thanks for the feedback!
