Its very fun for what it is, with a little polish and graphical enhancement this could make a very solid game as it has a lot of potential for expansion, like imagine adding a story for example. like i said many possibilities.
But my experience did come to a halt after fighting a battle in which neither sides could kill the other. So one suggestion from me is to maybe make the "give up" option more forgivable, like a debuff and not a full "back to square one" type deal.
But other than that, very noice.
