The legend of ninja

The legend of kage (影の伝説) - The player is armed with a kodachi shortsword and an unlimited amount of shuriken. Grabbing a crystal ball causes the player's clothes to change to the next level in colour and thereby attain certain powers (bigger shuriken or faster speed); if Kage is hit while in green or orange clothes, he does not die but reverts to his normal red clothes. Grabbing a scroll causes Kage to stand still and meditate for several seconds while approaching enemies drop to the ground dead (although the scrolls appear in the arcade version, the crystal balls do not).
