In this game you are in a position to save or defend your goal from the incoming balls that are shot and are heading towards your goal. So you are in the role of the goalkeeper and you'll see how fun and entertaining that can be instead of playing a standard football game in which you are always in a position to attack by dribbling, passing and shooting the ball to the opponent's goal. So, the controls in this game are very simple. Once the ball is kicked, you need to save it and by moving the mouse towards the ball and pressing the left kick in the correct moment you'll be successful in saving the ball. Have a good fun!
