Major improvements but still some flaws!
The game flows much better than the previous one. Much much much better. It's nice to not have to click 10 billion times to get stuff done. Everything's got a much better look to it too! Added customizability is lovely and can greatly ease adventuring. Thank you for that! The music is simple and pleasant. You don't really hear it but it does improve the feel. This is good. Music for this kind of game should do that.
The gameplay is addicting, and while some things aren't terribly balanced (mineral gain, buy/sell rates, etc.), investing time can fix that with pure waiting and adventuring. I do wish there was a way to increase mineral gain, even if it was expensive. The only MAJOR beef I've got with this game now is the foundry. You can only produce 1 iron per round, max, and it saps 10 for a meager one gold, which doesn't actually pay for the iron it's using, though I suppose one gold for 10 iron is gob-tons better than the selling rate. Still, lots of things work off iron and I'm losing 9 every round instead of gaining any ever. It's really harsh, but no research without it so it's a very necessary evil unfortunately.
Tips for improvement: When selecting units for adventures, make a basic toggle function. Clicking a unit selects them, clicking it again deselects them. A way to increase mineral gains (iron, tin and stone... Copper comes in pretty easily through other methods) but I would make it expensive so it's something to work towards and makes it harder for people to accelerate their town too quickly.
That's about all I can think of. Excellent game. Been looking forward to another one of these for a long time! One of my favs!
