This guy will be waiting over a short pit and trying to blow you away. Stay on the platform opposite him, and simply fire at him while jumping over his shots. Easy.

This guy fights like a ninja, except he's got a lot more life and throws more stars. Jump over what he throws and throw whatever stars you've collected at him. If you should run out, go up to him and start kicking him until he's finished.

Don't be suprised if you die quite a bit, he's pretty tough. He has a gun, but he prefers to kick. Before you reach him, you'll see two platforms, one that goes up, and the other, which goes down. Just jump on the first and wait for it to reach about the top of the screen, and then get a good jump so you land on the area next to Durant, who will begin firing at you or run up to you and try to kick you off into a pit. There's really nothing you can do at this point but fire your gun repeatedly and hope you kill him. If, and when you see him die, congrats, you beat the game.

Now lie back and enjoy a half-ass ending!
