This game is really addicting!
It took me a while to reach the "Ronin" rank and I'm still playing to beat that... frustrating in a good way.
Really like the controls and the gameplay. and the narrator is just brilliant!
Unlockable envroments and player skins would be a great addition.
If there's one little thing I would change, it the sound when you hit the shurikens with the sword. I would prefer a more "metal on metal" clinking sound instead.
Good job guys!
