Yellow stars are placed anywhere on the play field, some are closer, others are farther, but most of them are difficult to reach. You have a limited number of shots, so carefully calculate the power and direction of each ball. You are the only player, there's nobody to help you, only you, a few balls, and an increasingly number of obstacles between you and the targets. Try to use as fewer shots as you can to reach your targets, otherwise you will play again some stages.
If you fail the first attempt, don't give up, you already get some experience and chances to succeed next time are greater!
Controls: use mouse to interact, click on ball to shoot and collect stars
