Super Mario Maker is a video game that allows players to create and share their own custom-made Super Mario levels with others, as well as play levels created by other users from around the world. It was released by Nintendo in 2015 for the Wii U console and later in 2019 for the Nintendo Switch.
The Super Mario Maker font was custom made but Github user yell0wsuit recreated the font as MarioMaker. You can find licence information here.
