Such a well-balanced game. It's like do you want to have an easy fight and spend all your money on troops okay, but that means that three battles down the line you are going to be fighting harder enemies with one or two troops. To counteract the whole penny-pinching you can buy upgrades effects by killing enemy soldiers, meaning that all you really need to win a fight is one or two troops and a heck of a lot of battle strategy.
9/10 probably the funnest battle strategy game I've ever played and I hope Rrykos keeps on making such amazing games.
