this game does look kinda fun, and the amazon has a nice butt
added to my list of "games to buy"
This is from an actual NES digital game created by the company to celebrate the anniversary of its releasehttps://www.ancient.co.jp/~game/mamotte_knight2/
You can download the free ROM at the bottom of the page.
Also I forgot to mention that the main composer for these games, Koshiro Yuzo, is quite awesome. (Streets of Rage, Actraiser, Etrian Odyssey)
