Use the arrows to move the left line. 1 makes the left line the line it starts as and 2 makes the left line the half circle needed to trap the ball. The right line is controlled by the letter keys w, a, s, and d. 3 makes the right line the line it starts as and 4 makes the right line the half circle needed to trap the ball. If you trap the balls in between the 2 half circles as a whole or almost whole circle you win!
Thank you for playing this game. Sometimes when you trap the ball it glitches and the ball goes through the lines. This happens more when you trap it. Please post if you win.
