Controls are absolutely awful and unresponsive, It can take 5 or 6 goes to get the autosend arrow to come up. The tutorial was pretty confusing too. Not a bad concept but extremely badly executed.
Scratch my last comment this game is way too easy, you can create tanks that are just floating gun turrets? So easy to dodge other stuff yet you still have all the armor of a class 5. Ridiculous, breezed through the game without taking a hit.
As has been previously said, the colour scheme makes your eyes bleed after a while, the gun upgrades are pretty useless and ill thought out, it would be far more fun if you could get more gun points, and the lag in later levels made the game unplayable even on a new macbook. Had such high hopes starting out but later levels were annoying and laggy.
