At the request of SaikyoStyle here at YouTube, I present to you a video walkthrough / runthrough / playthrough / etc of the Sega Master System's version of Shinobi.
I almost had a perfect run, but I do get hit a few times....I even mess up at the last bonus stage....Meh.......So freaking close.....
As far as Mandala goes, I'm sure there's a better way of doing it, and I should have practiced more on that boss before attempting my run. Perhaps if I hit one statue, and while that was spinning, hit a different one. But, I still survived, so I'm happy... :P
What a great ending this game has, eh? :P
