I really enjoyed this for what it is; a beat-em-up with RPG and story elements. Each chapter is fairly short, which is perfect for a mobile device. You can pick it up and finish a mission in less than twenty minutes, or you can work on the jobs (kill a certain number of badguys, use a certain move a certain number of times, etc). It's slightly repetitive, but the story is good enough to keep me interested, and as you learn new moves, it makes Kunio feel like Batman with the fast combat. Definitely worth checking out!
