Does the #BackToBasics movement has really got me excited about Super Mario Bros. X again? Yes it does! This is another level I made which I think is really good. This time I'll take you into a dark brooding cave where Mario will face some of his toughest enemies yet! This level of course follows the official community guidelines, as all levels should. I think you're in for a lot of surprises and maybe even a bonus or two! Good luck!
