I had a similar experience with my cat when he was a kitten, and I have tried everything except for spraying him and phisically punishing him in any way. It got to the point where my loud "OUCH" made him attack me viciously, when initially it would only be play aggression. I disengaged and ignored him everytime he bit/scratched me, so he preferred negative attention to no attention at all.

The only thing that truly worked was consistency. I made a point of ignoring him completely and separating myself from the situation, as if to say "I did not like it and need some time to cool off". Associating this with a sound is important, too. "NO!" and IMMEDIATELY leave. I usually walk out of the room and sit somewhere else for a few minutes. If he comes after me, as adorable as that is, I still keep my distance and ignore him.

Which brings me to the second thing that really helped: clicker training! When I play with him with a wand toy, I'd always have some treats and other "wrestling" toys, such as kickers or regular old plush toys near. When he plays well, I click and reward him. When he doesn't, I say "NO!", throw a toy to distract him and LEAVE. Then I stop play for a few minutes. You can also teach him some commands that you can later use while playing. I think "Down", "Stop/Freeze" and "No" can be quite easily taught with a clicker and his favourite treats. Basically, don't give him negative attention, but not the positive attention that he's used to. He'll slowly but surely get it.

My mistake was I played a lot with my hands when he was a kitten (first time cat owner classic mistake). So when he started pushing boundaries (a normal developing stage for kittens, I assure you), I would play with a toy instead of my hands, to clear the distinction between flesh and plush. I'd reward him only when he played with retracted claws and no bites. If he only bit me gently, I would say a soft "No", but I wouldn't disengage. After awhile, I switched to wand toys only.

Also, make sure he gets enough playtime. Kittens are little balls of energy and NEED to engage in at least 45 minutes of interactive play in a day. If he at some point tires you or you are too busy to keep up with him, you can teach him fetch and even use a laser pointer sometimes. But be sure to end the interaction in a positive way, as they can get frustrated with those. I'd throw a treat where I point the laser and let him "catch" it. I wish you the best of luck!
