I found that the hands catch the ball more reliably when I press both arrow keys at the same time.

The scene would be a little more interesting (IMHO) if the user were able to change various parameters such as, the distance between the hands, the amount of throwing force for each hand, and the weight of the ball, etc.

Good ideas, feel free to modify and repost this scene.

I'm going to have nightmares with that fingers
Good scene, but Xray is right. you should add some parameters to make it more interesting
