Thi was a fairly fun game, but some parts confused me. The sound didn't work when I was playing the levels. I don't know how this happened, as it was working just fine with the cutscenes. Anyway, it's great that you combine zombies with ninjas. There should be more games like that. The most frustrating thing was probably when you weren't supposed to cut the bread and you had to just let it come to you by hovering under it.
I really like the graphics in this, particularly with how the ninja throws his sword around. It's disappointing I wasn't able to get a medal with a game that has so many. The sounds (what few there were) were decent. It's a playable game and should be good for ninja fans. It's pretty clear cut in terms of understanding.
