this has the potential to be a very good game, love the graphics etc, please read the constructive elements below and make a few changes, make them quick though i really want to play this game when it is sorted.
\thi game has the potential to be great with some work. ideas: when you destroy obots they occasionally drop a weapon or something which as your robot pick it up upgrades it. better cash injection. obsticles so you have to move your robots. towers you can add to battleground for support. mixed robot attack. a boss 3/5 would be 5 with the upgrades
