Amazing!
Though rough, this has to be one of the best game ideas I have seen out there. I like the bouncing colour balls especially. Don't know what that other guy's saying...
Suggestions:
- add different options to your tanks' movement, like Roam, Patrol or Follow modes
- I personally would like to be able to keep what I buy from level to level. I always liked games that let me build up and maintain an army instead of replacing it all the time
- add upgrades for your tanks!
- make a limited number of tanks and link them to hotkeys
- i think it'd be cool if you hold down your mouse and draw a path for the tank to follow.
- add other things than tanks, like immobile turrets or one use airstrikes or something.
k, that's all i can think of right now.
