Ok this game is a bit weird. Ur supposed to be playing a samurai, but in reality u look like a ninja, out to kill all the emperors men and to steal all the sacred scrolls. Maybe ur a ninja-samurai... that might make more sense. In any case, to succeed in this shootem-up platform game, use your shurikens and powder bombs to destroy everything around you! Defend yourself from angry red ninjas, and find all secret scrolls on each level.
Carve ur way through the castle with explosives and ur special explosive tipped shurikens. U can destroy basically anything in ur way... but don't go nuts with it, otherwise u may find urself without a path to the level exit.
