Welcome to Super Mario Maker! I will teach you the controls, The controls are quite simple to move you can use the arrow keys or the wasd keys! To jump you can press the up arrow if you are using arrow keys or W if you are using wasd keys! To shoot fireballs as Fire Mario, You can use the X key, To open the editor press 0 key Not "O" its "0" make sure you remember that! Enjoy! :D
@griffpatch for the AMAZING tutorial! Nintendo for the creation of Super Mario! That's about it!
