Query: Shinobi is Hard, but fun!

Shinobi is one of those games that won't let you through a stage until you master it. If you want a good game with high difficulty then shinobi is you game. Also if you collect 40 orobo clan coins scattered throughout the game you can play as the original shinobi--Joe Mushasi.
