I would love to see you re-remake other G&W games as well, especially ones like "Fire" or "Mario Bros". They don't even have to be Nintendo branded, you could use newly-public domain characters like Mickey and Minnie Mouse instead.
Edit: Heck, you could remake the entire library that way, and sell it on Steam/Itch.io/GOG!. I'd gladly pay for a full collection just as wonderful as this, without Mario attached.
