The Legend of Kage

The player takes the role of a young Iga ninja named Kage ("Shadow"), on a mission to rescue Princess Kiri (hime) - the Shogun's daughter - from the villainous warlord Yoshi (ro Kuyigusa) and fellow evil samurai Yuki (nosuke Riko). The player is armed with a kodachi shortsword and an unlimited number of shuriken . Kage must fight his way through a forest, along a secret passageway, up a fortress wall, and through a castle, rescuing her twice (three times in the FC/NES version) in order to win the game. Each time the princess is rescued, the seasons change from summer to fall to winter and back to summer.

In home versions, grabbing a crystal ball causes the player's clothes to change to the next level in color and thereby attain certain powers (bigger shuriken or faster speed). If Kage is hit in a home version while in green or orange clothes, he does not die but reverts to his normal red clothes. Cycles repeat after five levels are completed, and play continues until all lives are gone, which ends the game.
