It’s a fairly decent game, but there are some calssic issues where the game won’t recognize what you want with your motions on the screen. Given the type of series Ninja Gaiden is, it can be very frustraiting.
Found my DS and played to the end of level 4... I agree with Forlorn. I like the game for the most part... and lauged at a few points where I wanted Ryu to go one direction, but he went the other. I laughed as it brought back old memories of Ninja Gaiden for the NES and its controls being a little "off" at times. (anyone remember the last level? I was killed more often from mis jumps then anything else) I would reccomend the game overall as it plays a lot better then I imagined. I had some issues with getting hit from offscreen enemies at times also.
