Ninja gaiden was the hardest game in nes known for its frustating enemies. But author manage to make it easier. Movie obsolete nothing but still good to watch.

I used shortcuts , glitch, abuses programming errors.

With up+down+left or right+left you can move backward

if you press the forward button screen in ladder you can zip inside the wall.

FractalFusion: Judging.

NitroGenesis: Removed useless branch and corrected game name.

FractalFusion: It seems the author is planning to make a new version, so I will cancel this submission.
