with duels, both teams should start with nothing but the building center. you should also be able to build more building centers, and there should be a multiplayer. really fun game, great job making it. 4 out of 5.
there should be bigger win bonuses and you should be able to drive your dead tank around but not shoot. also, there should be challenges, such as-kill someone with a sniper shot or something like that. a different way to get tank coins instead of wasting money
