Original game, where your tank is indestructible and the only way that you have to beat the enemies is to propel you with the explosions of their bombs to hit them. Let the bombs fall over you, because they cannot destroy you. After they do it, your tank will be launched in the air, and your goal is to hit all the helicopters you can. If you hit many of them in a single jump, the points you earn will be multiplied.
Arrow keys to move, both on the ground and in the air.
