Great game, for those people who dont know how to turn down the graphics, during game play press space bar, then at the top right it will say options click that then turn down the quality/graphics. It took me a while to notice this, just thought i would say it
I've beaten impossible, by the way if you press space when your building units it will pause but your units will still build,you can make all five units before the enemy moves an inch,
I think it was a good game, one problem though a couple of times i killed one of the guys, all of their letters were red x's, but they still kept running and took down health on the shrine, its a minor thing but still annoying, still good though
