Move your mouse over the ball to aim, click to shoot.
This was the foundation for a game which I lost motivation to continue with. The idea was to make more balls appear as the difficulty increases, but I then realised that aiming is a problem with more than 1 ball.
Sorry but I'm not a teacher. When I was about 13 years old I went out and bought a book on Flash Actionscript 2, if you want to learn I suggest you try that.
Please
