Yeah, this game is pretty good. Fairly inexpensive, optimized to take advantage of the Play's buttons. I enjoy it quite a bit. I couldn't imagine doing this with the touch screen. It would be so unintuitive and I would constantly get in my field of view due to large fingers.
I have thoroughly enjoyed this game and would recommend it to any person that likes action games, provided they can withstand a little cartoony gore. (Beheadings, Sliced in half laterally, sliced in half vertically, lots of blood from kills which does fade away).
