Players are hanging out in stores nationwide to check out the new Super Mario Odyssey demo, a 10-minute trial that has enormous speedrun potential. A new category has already sprung up, just based on what’s available at these in-store stations.

A number of speedruns are available on YouTube, all shot with handheld cameras and captured in stores. A person who goes by Fengari ran through the demo’s world, the sandy plains of Tostarena, in just over seven minutes, others have tried to best him with their own attempts.
