Become a master of ninjas and save the princess from confinement. The game is not infinite and if you have the patience, then you will see the final of the story. Your main ability is a lightning strike. But in order to inflict it, you need to wait for the right moment. Watch the plates with enemies that move up and down. Once they form a single line, click on the screen and make a lightning strike with a sharp katana, leaving only a spray of blood.
