A captured ninja is useless to the world. So break free, escape, and punish your captors with the brunt of your ninjutsu skills. There's no amount of ninjas that will escape your revenge, but first you'll need to force them out of hiding. So run, ninja, run. And prepare for the slaughter.
Use the Up key to jump and double tap for a double jump. Use the Down key to slide. Attack enemy ninjas with SPACEBAR.
