Fighting is all the ninja got.It is a combat and you have to steal the money and defeat your enemies.It is like an adventure.You are alone in the combat and you have many enemies so try to be strategic in your plans.It is a level based game.You will enjoy playing it.Good luck.
Use arrow keys to move forward and backward.Use X key to attack your enemy by your sword and use C key for jumping.When you will kill all the enemies you will go to the next level.Have Fun!
