Sounds: The sounds were completely together with the confept of a ninja sneaking through the enemy base at night to rescue the princess.
Controls: The controls were easy and simple so it was fun playing it.
Concept: It was a pretty simple concept, saving a princess using stealth and ninja skills but it would have been better if there was a twist in the story line.
Graphics: It was simple but it would've been better if it had a little more 3d effect on it.
Gameplay: It was really fun playing it because you could really see the cool and out of this world skills of a ninja like running up a wall and bouncing from rock to rock.
Overall: Its a great game my friend! The way you turned a simple concept into an enjoyable game because of the insanely cool skills of the ninja and simple controls of the game.
