Great concept, lousy controls. Fun and addictive. Made it to level 49 before I gave up. This would be a lot more enjoyable if the controls weren't totally terrible, unresponsive, and unpredictable.
Good but too difficult by levels 70-80
Controls suck. My tank never does what its supposed to do. The white tanks never die and keep killing me. My tank sometimes also dies for no reason.
