^ Wow, harsh. Seriously you gotta chill, he came here to get some feedback, not have someone demoralize him. Also, if you're not saying it to be mean, then are you saying it to be nice to him? I didn't think so.
Anyways, there is one thing I agree with scotu. You really shouldn't play level 9 CPU's as they develop bad playing habits. If you just have to play a CPU, play level ones as they are easy to practice your technical skill on, but don't get to used to that either. Also, you might want to work on wavedashing, and SHL'ing lower and faster. Work on some SHFFL's too, and you'll get better in no time.
