Play as ninja running in high speed over roofs. It's not easy at all because when running you have to get over many pitfalls and some enemies. I place this game among the simple games. But not thanks its difficulty. The enemies can be jumped over or slashed with your sword. To be able to attack you have to find the sword at first. The holes, where you can fall, happen so often that you have to sometimes fight. The game is quite difficult and one mistake means game over.
