Press the 'S' key to start or select a level on the Overworld Map
This is one of the most incredible flash games to have ever been made. It autobuilds entire Mario worlds for you to play! Each overworld map and each subsequent mario stage is built randomly so you never play the same game of Mario. The game itself plays like Super Mario 3 on the overworld and a stripped down version of Super Mario World for the actual stages. There are multiple themes here too from the Donut Plains to the Underworld Caverns.
