Aim for the better color first. New colors give more points shot, as well as more balls if any are present. Always shoot the best colors first before targeting lower value colors. Shoot the shapes that contain hearts and balls first before the empty shapes that are only worth points. Do not rely on random hits. Always try to hit a specific target. One good strategy is to your balls into the sides of the screen at the top. If you miss, they will fall down and may hit a shape on the way. Wait until the shapes begin descending to shoot so you can anticipate their movement and be able to target them correctly.
