There’s some types of videogames which struggle to make a transition to a handheld format and some where, once they make the leap, feel like it’s almost their natural home. I’d include traditional, old-school platform games like the 2D Mario games in the latter category. Their clear, cartoonish graphics translate to smaller screens nicely, the gameplay is simple enough to not require particularly complex controls whilst having enough wrinkles to stay challenging, whilst at the same time the level structure means you can pick up or put down the game at a moment’s notice.
All this makes it rather weird why it took so long to get the handheld versions of the Super Mario Maker games right. The full-fat console versions (released on the Wii U for the first game and the Switch for the second game) provided a nice system for designing homebrew Mario levels based on the gameplay and physics of several different Mario games (Super Mario Bros., Super Mario Bros. 3, Super Mario World, New Super Mario Bros. U), publish them to the Internet, and download and play other people’s levels. Should be simple, right?
