The number of courses you can upload in the Super Mario Maker 2 course designer has just been doubled. You can now upload 64 courses, up from 32.
In the “News” tab for Super Mario Maker 2, an important notice from the developers now says that the “maximum number of courses that you can upload has been increased from 32 to 64 courses.”
This means players and course designers can now share more of their work online at any given time. Nintendo also says that it plans to increase the course-upload limit one more time after this, so there’s a chance this number could double again.
Nintendo also announced that over 2 million courses have been uploaded already. That number will likely grow now that the course-upload limit has been raised. Players have been creating some very imaginative Mario levels, and a quick crawl through the Mario Maker subreddit will uncover some hidden gems.
