Fun but frustrating--your player often turns the wrong way for a shot. For example, the character will try to return backhand from the forehand court even if she's lined up with the ball straight on. This can be tricky, especially if you're trying to control the angle of the ball with the arrow keys as you swing. Ditto the other comments about the difficulty in controlling with the arrow keys as well. Any possibility of mouse control?
