Huge minus because the AI is rubbish. After losing several time simply because orange decided to send all its fighters away when it was attacked it stopped being fun. Another minus because I have played several extremely similar games most of which had better game play, level design, upgrades etc.
Ideas to make it better:
-ability to stop troops already on their way (look at tenticle wars for example)
-AI that doesn't simply try to send all its troops away as fast as possible
-different kinds of cities (some with higher production rate or defence, maybe towers of some kind)
-look at similar games and try to improve what they do instead of using only their core mechanics
the gameust doesnt make sense it shuld have upgrade menu
The entire game just seems poorly made to me. There's a significant chance that sending troops just plain fails to work, which frankly is enough to ruin the entire game by itself. The graphics aren't very good either, and there's a serious lack of features.
