THIS IS HOW YOU WIN EVERY LVL EASY: drive straight to the end of the lvl without picking up any minerals, once your there drive on top of the crates and or barrels and accelerate, shooting them underneath the truck (usually about 1 or two) then back up slowly into the magic beam thing, and it will take the crates and barrels and give you a speed bonus, + you win in like 15 seconds
right click forward, then restart fast, and yo u keep all of your army for the next game, and it resets your max units, reapeat this process and get hundreds of cannons to destroy their city in one shot its fun
some people need to realize that when you have hundreds of balloons stacked up, and a mine hits you, it pops huge amounts of them, and thats why you lose so much height
somethings messed up with this game there i found this wierd item with no name that flashed all the items in the game really fast over and over and when i bought it i blew up and died...
