Kicking the soccerball: To keep the ball in the air you have to click on it at the right moment. The first kick is the hardest. I don't know if it has it's own moving hitbox or if it's static around the resting position. In any case, don’t move your mouse. Also, turn off any music you have playing in the background. Also turn off your lights. No Distractions. I found it easiest to look at Mellow's eyes to time the clicks to get a hang of it. They have three positions when the ball is in the air, top, center and bottom, corresponding to the ball's vertical position but simplified You have to click the ball when the eyes move from the center to the bottom position.
