This game isn't really as hard as you think. You just have to know the concept of zoning, and (maybe) get used to his attack patterns. Beat it on second try on medium, got to the pearl laser on the first try.
It would be AMAZING if when you lunged into an enemy that was lunging at you, your swords would clash and you'd have to buttonmash or something to break the swordlock and kill him.
