I assume Warzone is one of your main references for your game, otherwise I would suggest playing up to bottom and upside down to know exactly what to improve upon it and make your game different enough. But the main problem of Warzone in my opinion is the path finding where your own units doesn't consider the path of each other and end up colliding constantly. 50% of units lost are because of that.
I don't know why but the reply box in itch have the line breaks completely broken xD
