Press the green flag. The ball will point in the direction of the cursor. Press space to shoot the ball in the direction it is facing. After your shot, press "r" to see the slow-mo replay. You can watch the replay as many times as you want. Press the flag to try again.
The box in the top left hand corner says the amount of goals you have scored. I was inspired by the project SCRATCH Movie Maker. However all the coding is by me.
