This game took just under 3 hours to beat. This level took around 1 hour 24 minutes. I practiced the final boss with save states , but wasnt recording that practice, so a rough estimate of 15-20 minutes practicing that part, plus the rest of the recorded time comes to around that total.
I executed much better on the final boss in practice but here it was sloppy. Regardless the general strategy was to get inside his body when he is about to appear on the ground, after teleporting, then doing a punch combo. By doing this he wont be able to hit you and one of the hits of the punch combo will make contact with him and knock him back.
Aside from that I used tornadoes whenever he was floating in the air. I tried to do them immediately so he couldnt get out moves. When he throws his weapon I jump it and try to land a jump kick on him.
The rest is just muscle memory and practicing. Hes not too hard but one of the harder parts of the game. The section previous gives you a one up every time you start it over, so you can just keep starting from there. Youll see the techniques I used to clear out the enemies in the enemy rooms. It minimises damage so try to follow that.
I may beat some others in the series and the one on PC FX in future videos.
