Since its release back in June, Super Mario Maker 2 has been giving Nintendo Switch players to not only craft their own Mario levels of their dreams, but also to experience the creativity of other players around the world. Given that the Switch has also been the home of a growing indie development community, it only makes sense that Nintendo would highlight Mario Maker creations from indie devs, including the makers of a cult classic.Over on Twitter, Nintendo shared a new level in Super Mario Maker 2 made by Sabotage Studio, the developers of last year's acclaimed The Messenger. Titled "The Key of Adventure," the course not only should be a challenge for players of the Metroidvania-style game, but also includes hidden rooms and challenges, and several Easter eggs that fans of the game should enjoy trying to find while playing. You can find the course code for playing it on your own below.After its release, the Mario Maker 2 community has already been off to a great start with over four million courses that have been created (as of July). Some of the most devious creations that we've seen so far include this particularly stressful version of the iconic 1-1 stage from Super Mario Bros., along with a (now deleted) level that was inspired by the infamous Raid Area 51 meme.Super Mario Maker 2 is available now exclusively on Nintendo Switch, while The Messenger is available now on PS4, Nintendo Switch, and PC.
