Same. If we ever get another Wario Land, I really Hope they bring back the different difficulties. It worked then, and it worked for Metroid Dread, so I have no doubt it'd work again.
If any one of them make a return, whether it's in WarioWare or Wario Land, I'll be mad happy!
Also that's cool fact about the Ghost Pirate I didn't know! I think I actually like Captain Coin better.
You can also press x to jump too. It may not be the iconic jump button, but at least you can still use your right thumb to jump if it's that important to you.
