Sneaky Ninja is a side-scrolling arcade action platformer with stealth elements. You will play as a secretive ninja master who somewhat resembles a sock rolled up into a ball. He has many skills, the ability to kill opponents by falling on their heads and a good sense of humor. For over a hundred years, a small village inhabited by ninjas has flourished peacefully in the Udon Groves forest, protected by the magic of the spirits from the warring army of samurai. But one day the magic mysteriously begins to disappear, and samurai invade the settlement. You will join Taro and his fellow ninjas to restore the power of the spirits before the samurai destroy all ninjas once and for all.
