The Pixel Knight has returned to fight off monsters through 16 maps. Use the arrow keys to move, with the up arrow being jump. Press Spacebar to fire your weapon, or the X key if it is easier for you. Once you have lost your three lives, you can either submit your score and start all over again, or start only that level again, and not have your score submitted, depending on whether a high score or advancing through the game is more important to you. As you progress in the game, you will also earn more weapons to use.
