Best Flash Game Ever: Indestruc2Tank

I've already wasted way to many hours on this. Basically you drive a tank, but purposely hit bullets to launch you into the air. Once in the air, you try and bounce off as many planes as you can without hitting the ground. The more you hit, the more experience points you earn, which allows you to buy more planes to attack you.

Sounds wierd, but trust me, its a good one.
