It has a unique control scheme that's strange but it's not bad. I can hardly find the words to describe the controls, but it seems like context sensitive touch based gameplay that I see a lot of people not gel with because Ninja Gaiden is about high-skill precise timing, but it's a DS game, dog. It takes the gimmick of the DS touch stuff and runs with it in a way I find entertaining.

I don't know how the fuck you can emulate this thing. It's definitely worth at least checking out if you have the hardware to do so.
