Super Mario Maker 2 adds World Maker mode for building entire games

Nintendo has announced what it describes as the final update to Super Mario Maker 2, and it comes with a huge new feature: a World Maker mode that lets you design a map and string multiple courses together, Super Mario World-style. Each world can contain up to five levels, and eight of the worlds themselves can be combined, meaning you can create your own 40-level Mario game.
The update also includes the addition of several new enemies and power-ups including the frog suit from Super Mario Bros.
