I was thinking on do a Run of Story Mode Any% Luigi assistant, I like the idea of the assistant lol :V

I who levels are used the Luigi assistant? Would be nice to learn the differentes parts of the Luigi assistant category and the no Luigi assistant category

You let Luigi finish the final level for you. I don't think there are any levels where dying twice to unlock Luigi's assist parts would be optimal, unless you die 1-2 times accidentally which actually happens to the best so you might find some use for it

Yeah, this is true
