It was announced earlier this year that Nintendo was officially supporting GameMaker on the Switch, an engine used for games like Undertale, Minit, Hyper Light Drifter, and more. The support opened the door for a lot of indie games coming, as evidenced by Switch ports of Undertale, Minit, and Hyper Light Drifter. When the deal was announced, both Nintendo and GameMaker company YoYo Games planned to make it even easier to get games on Switch by hoping to integrate a “Port to Switch” button.
The new version of GameMaker Studio 2 is in beta and finally incorporates that useful option.
If you’re planning to make a Switch version of a GameMaker game, it no longer has to be done independently of the rest of your work. You do still need a Switch license and be approved as a Nintendo developer beforehand, but the work was at one point a lot harder than it is now.
The Switch version of Minit released today, Undertale is scheduled for September 15 in Japan and should be at a similar time in the west, and Hyper Light Drifter should release later this year.
