Ninja Warrior is an arcade game where you go through various levels (designated by your karate belt color), each of which adds more difficult obstacles to get around. You can kick (or use your trident) to destroy rocks, opponents, fireballs, arrows, and other things that will cross your path... and you can also jump over holes and some of the obstacles. Although the game ran in quite a low resolution (128x96x4), it was actually very fun to play.
