Frustrating
Know how much it sucks to be sitting there watching your army get wiped out by a mortar shooting enemy on a hill that you can't reach because your own troops shoot mortars that don't go far enough to reach that blast you back. I actually got stuck in a never ending blast recoil loop from this, being tossed back and forth like a volleyball.
The game has promise. But as it is, the campaign is very short, and the ally AI needs work, and it would probably be good to turn off friendly fire. Those tank things are way too strong too. Or the aerial support needs a buff.
