how do i beat nell?

Well, i'll just get straight to the point. Nelly is a left-handed table tennis player, so when you aim the ball to the left side of the screen, she does a backhander. She is a tiny bit weak in her backhander, so try to hit forehand most of the time, and when you need to aim to the right you put backspin on the ball, making Nelly run to the right and easily hit the ball back for you, then you all of a sudden do a fast ball to the left, and two things can happen, one, fortunately for you, she barely hits the ball and you smash a backhander to the right, and thus, send her back and forth, eventually missing her backhander, and you gaining a point, or two, she hits it back with tremendous backspin, and she will hit with her killer topspin after you return the ball, what you don't want to happen, so you do a quick topspin to the right using a backhander, and the ball will, hopefully, barely go over the net, and you gain a point. The latter is really hard to do without missing, but sometimes it works, if you don't want to risk that you miss the ball, just hit the ball to the middle of the table nd start the cycle again... Backspin, quick leftie, smash right, smash left, and eventually she'll miss. I'm telling you, this is freaking hard to do, it's the hardest 'boss' in this game.

Long answer huh? I hope you understand it :P
