Maus Force Attack

How does the game Maus Force Attack work?

Fly the plane that shares qualities with the heaviest tank, the Maus. Your mission is to reach the end of the level, beating hundreds of enemy planes. However, numbers don't matter, because of your skill at the controls. Use the A key to shoot and the spacebar to drop bombs. Collect the items that the enemies drop to get more fire power, lives and bombs.
