The idea of the game is quite good. The graphic quality is really great and is pretty smooth. The name decribes the main idea of the story really well. Its idea is also quite innovative. The game has plenty of levels. The weapons are also good. But they are not much.The background music is great.The few bad things are that it does not take too long to finish the levels. The Ninja moves are not too many with only a sliding kick and a downward kick. A high fall can nearly kill the player. The weapons are not many but they are quite good. The skill levels are not very difficult to master. But the idea of the game is neat and clean. The game is well made and is a sort of stripped down version of other side-scrollers like Jazz Jackrabbit and Sonic.
