Maximizing your fun:
New players should visit Mushroom Land, which is the most complete area in the game world. Press your character against a tube to test it and see if it goes somewhere. Press up with your character against bricks with exclaimation marks for helpful hints.
This game is made for multiple players, but many of the single player elements from the Mario games are also included. This means you can play the game alone, without any other human players. However, I suggest that you send a link to this page to all of your friends, and see if they would like to play with you!
Instructions
Use WASD as your direction pad. Hold K as you run for additional speed, and press J to jump. Press enter to open an chat text box, and press enter again to send your text to other players. Hit boxes with exclaimation marks on them for more details.
