This was definitely a fun, albeit short, game! There isn't much to criticize here! The multiple endings does give the game plenty of replayability, which aids in making this very short game much longer and enjoyable!
Playing this makes me wish there were more "Age of War" like games, or more simulation-like games with armies!... Moving on though, having sound effects or "attack sounds" for units when they swing their weapon or something would've been nice. Amongst other sound effects for abilities and whatnot. Not much to complain about for a free game tho :P
