The Legend of Kage

The Legend of Kage is a port of the 1985 arcade game under the same name.

The player is armed with a kodachi shortsword and an unlimited amount of shuriken. Grabbing a crystal ball causes the player character's Kage's clothes to change to the next level in colour and thereby attain certain powers (bigger shuriken and/or faster speed); if Kage is hit while in green or orange clothes, he does not die but revert 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.
