I completed the story mode playing as Wario. It was a daft little story intersected with playing a battle version of Dr Mario. Whilst it was compulsive stuff, it was quite difficult but I soldiered on and thought it was ok.

I think I prefer the NES version of Dr Mario. I played that loads when the NES app was launched on Switch. There's something about this version that hasn't quite clicked. It's pretty much the same game only with added functions and jazzier graphics, but maybe I just prefer the more basic version.
