Extend the AirRaid game, so that the planes drop a bomb on the gun as they go over it. The gun has to move out of the way otherwise it will be destroyed if hit. Provide three lives in a game. Indicate the lives with icons. Assume the player has an infinite number of shots. The player cannot shoot down a bomb. Provide animation sequences for the explosion of the bomb. Also provide sound in the game, for the gun shots, and the explosions both for the planes and bombs.
