This is a VERY cool concept! I am really amazed by how the fact that turrets would destroy each other if they were too close changed how I placed my buildings - I ended up putting factories on the outside edge so that they wouldn't get Lasered, and I bet that walls could be used in really clever setups to increase building density. It was buggy, and the ui could use some work, but this could easily be developed into one heck of a game. I loved it!
