If you play this game on normal or ninja dog mode, it's absolutely fair and fun. Imo this game has the most realistic gameplay in all of the hack and slash games. Music is great, level design is not bad, gameplay is fucking amazing, story is decent, bosses are... meh. The only BIG problem is the difficulty. This game is probably the most unfair game i have ever seen in my entire life. For example in every level you get a shop for buying life regeneration items etc. but in the final boss area there isn't any shop. Why the fuck did you guys do this? There are some stupid difficulty, unfairness and unforgiveness problems in this game, but if you feel this game is hard for you just play it on Ninja Dog. Then you can finish it in normal mode, trust me. I have beaten this game in Master Ninja mode and it's SO FUCKING HARD AND UNFAIR. But i managed to kill final boss with no damage so start at ninja dog, then work your way up to hard mode. Very hard and master ninja are truly shit, but difficulties below them are not THAT hard. So if you're a hack and slash fan and want yourself to get ass kicked, this game is exactly for you! I strongly recommend it, even with it's stupid difficulty.
