Your mission in this ninja online game is to use your ninja skills to slaughter all the enemies. Use LEFT and RIGHT ARROW KEYS to sneak around, UP ARROW KEY to jump (tap it again while in the air for double jump)and DOWN ARROW KEY to duck. Press "A" KEY to throw a shuriken. Press "S" KEY to strike your sword. You can use your sword to dodge the incoming knifes and destroy the wooden boxes. These boxes contain items you can collect, but be careful sometimes the content may be dangerous. Press "D" KEY to release the great powers of ninjutsu (use it wisely because the amount of it is limited). Good luck!
