I like it
Knowing the KOF series as I do, this perhaps means more to me than it might to others. I wish he had those super extended moves int he game, although it would get quite annoying should someone to it to you!
It would have been nice if they didn't all end with the knife attack, or if you had some variations on it, like the victim falls apart in different ways instead of just collapsing.
Also, if that disclaimer at the start is serious (and not a joke), it isn't needed. No one is going to get offended by that.
