Final Fantasy fans?

Blahh.

So yesterday after school, I went to Gamestop and bought Final Fantasy: Dissidia. I chose to play as Cloud, as he's my favorite Final Fantasy character everrr, and got to the part where you fight Sephiroth. I've lost... ten(?) times now. I'm getting really, really, really, really, really, reeaaaalllllyyyy pissed.

Its like, I'll get just one hit away from killing him, and he'll turn around and kick the living shit out of me. So... I'm taking a short break...

Anyone here who played Dissidia and had similar difficulties? How can I beat him? Any advice for me?
