Cannon War

Cannon War is a shooter game where the player controls a cannon along the left edge of the screen. Other cannons will appear from the right side and shoot towards the player. If a cannon ball reaches the player's border he will lose a life and therefore it's necessary to shoot them down before they do so. The player can also attack the enemy cannons but to do so he has to move forward from his starting position into the screen and from there shoot at the enemies. Being stationed in the middle of the battlefield makes defending the border harder since there is less time to move the cannon vertically. Destroying a cannon ball is worth five points while destroying a cannon is worth twenty. At 500 points the player gets a bonus cannon. The game ends when all the player's cannons (three at the start) has been destroyed.
