Is Sun and Moon the game where it was on GBA and sunlight affected it? Konami game, I think? Always wanted to try it.
Super Meat Boy is fun, but really more of an arcade-y experience. It's a platformer, but otherwise I wouldn't really compare it to Shovel Knight.
Haven't played Super House of Dead Ninjas
I think Rayman Legends on PS4 is really good, have completed all the main paintings, and still go back to complete the Origins paintings I unlock. I still think Shovel Knight has enough charm to hold its own though.
Never played Ori or N++ (which looks to me like a lower-res Super Meat Boy kind of game), or most other games you mentioned.
I would consider Guacamelee in basically the same league as Shovel Knight, and I honestly think I prefer Shovel Knight more as a more pure platformer, where Guacamelee is more of a Metroidvania.
I think Shovel Knight is at least as good as, if not better in some ways, all of the ones you mentioned that I've played. I don't have much NES nostalgia and even with the SNES, nostalgia won't get me to care about a game. I still say Shovel Knight is notable on its own merits as a game. Agree to disagree.
