GDC 2024, also known as the Game Developer’s Conference, is currently underway. Not only is Nintendo there, but they even hosted a Super Mario Bros. panel. Wonder at an event earlier today. There they revealed some details about the 2D Mario game that some of you might be interested in.
At the panel, Nintendo revealed some content that did not make it into the final version of the game. Among the cut content were detailed concepts and prototype levels. One prototype level, where Mario transforms into his classic pixelated look with a big head, was far enough along in development that Nintendo showed footage of it on panel. Below you can see a video of a Twitter user who attended the panel.
