SM3DL 100% Route

A,B,C refer to the 1st, 2nd, and 3rd coins of a level, respectively.
G refers to the golden flagpole for a level.

I haven't put that much work into optimizing the details to be honest, I did a lot of "educated guesses" as to what was faster. It's a start though, and suggestions are welcome.

Also obviously I did not use any p-wings in this route. They probably save a lot of time. They're also dumb. Let's just require shiny stars imo

Use a red shirt mii. (I haven't tested this at all, I'm just stealing it from warpless)
