Awesome.
I loved the game. The lack of unit control is irksome, but other than that negligible problem that doesn't detract from the awesomeness of this game there was nothing I would change.
I found while playing that one of the most important attributes was command. At the end of the game, I had 10 command and that let my summon so many lichs that none of my guys would ever die (except on the demon level and the last human level). Basically, I'd enter with a lich, a skeleton, and a giant. Throughough the course of the battle I'd spawn 6 more lichs and end up with a huge force of 7 lichs, 1 skeleton, and 1 giant. The lichs basically stun from a range and dish out constant damage while the giant and skeleton pummel without taking any damage. Usually everybody survives, but I had to lightning storm the demons and the king survived on 1/3 health with two easily-defeated knights.
