One of the things about this game was that the action itself wasn't explained, but it required you to get momentum in the sense that once you started moving and acting it was easier to think on your feet. Many of the enemies all had a pattern of attack, but as the ninja you had to be careful not to accidentally push forward on the analog stick or risk moving into them as they pathed.
I enjoyed the music most of all, but the game play itself was satisfying as well. I'm more geared towards improvement, and I think instead of immediately maxing out the means of damage taken before the ninja is destroyed, number of special weapons like the shuriken, or max shurikens is where the game could benefit the most.
The platforming felt fair, and the diversity of enemies was enough to keep me on my toes.
