The game is great in itself; however, like everything great, it has its fatal flaws. Firstly, the AI seems to be very imbalanced – it never runs out of miners nor gold. The upgrading system needs to be improved, ASAP. You can't go undo upgrades or go back – it really narrows down the replayability – if there is any – of the game. Finally, the soldiers need health bars, methinks. :) Overall an amazing game. Thanks again, Crazy Jay!
