one of the best games ive played lately...a must buy!!!
also, even though hints are given through a kunai knife with a flower on it, the game makes u think a little for example say to get up to a high area there isnt just goin to be platforms to jump on you will have to run up walls and go to new areas to find other areas so basicaly nothing is given to u straight.
boss battles can be hard at times but even if u loose u jus feel like u want to play again until u beat the boss. whats good is that there is always a shop and a save point near a boss battle so that you can stock up on health items and save your game.
there arnt realy any downsides besides dodgy camara angles and a few glitches.
if i were u go out and get this game now! u wont regret it unless ninjas and fighting arnt ure thing.
