@CluelessWonder - The controls did change with your mapping, but the label doesn't. I was able to use My up arrow (replaced Z) to shoot even though it was labeled "Z" still.
In case you were wondering ... The unique units are: Kraig (Knight), Whitney (Crusader), Espino (Wizard), Lazaro (Cleric), and Bowen (Sniper). I just completed the game in year 1. (After several attempts.)
Great game. Only reason I'm giving it a 4 is because of the Fog of War effect and the controls were a little clunky. Would have been nice to have my mouse be able to scroll the screen once it hits the edge. Other than that, great game!
I gave it a 3 outta 5 'cause there was no way to mute the sounds in game. I wanted to listen to the music I had playing in Pandora. Grrr... Fix it and I'll up my rating.
