Good game
Needs some tweaking, but overall its a pretty good game.
Problems with the game....WAY too repetitive. Very little difference from the first battle you play and the last battle you play. Upgrades were pretty unclear, hard to know how much an upgrade would help you and therefore its a guessing game which upgrade is worth it. And upgrades were unbalanced..little reason to get market fair value and tower defense/offense for example.
"Pillaging gold" is pretty broken, too hard to get gold without it, too easy to get a ton of gold by rushing a thousand units down one line in an easy battle. Potions were overpowered....too easy when you use a potion and too hard late game when you don't have a potion.
Virtually no penalty for losing a battle. And you're pretty much forced to keep all your heroes together which made things less boring.
Overall the game is still pretty good, however if these problems were fixed in a sequel this game would be so much better.
