He's really annoying
its good for what it is as a point and click adventure, he really needs to sharped those arrows. The game is ok, really obvious in a way that makes it feel like its for children. If you have to enter a code its probably written on the thing your about to use etc. But clearly some people like the guy below me couldn't figure it out... you can't win I guess.
The guy himself is really annoying though, I've never heard a ninja make that noise.
-1 for annoying noise
-1 for in game adverts
-1 for over simplicity
other than that a good game
