Hung on a tree wooden shield. You are taking aim with a special aim and shoot the shield. Your task - to get to the center. The catch is that the shield is constantly moving. He swings on a tree to the left and right and it does not give you the exact aim, so you should consider this fact and shoot with a small gap in time, so that the projectile flew on time. Shoot and aim with the help of your computer mouse. The more times you will find yourself in the center of the shield, the better.
