Sir Lancelot

A damsel in distress is being held in a castle by a fire breathing dragon! As Sir Lancelot, you need to ride to the rescue. Each level in this action game consists of two screens. First, you are outside the castle which is guarded by numerous flying creatures. You need to fly around the screen and destroy all of the creatures by hitting them with your lance. If you can defeat the dragon, the game repeats at a higher difficulty level. The game ends when you lose all of your lives. (mobygames.com)
