To play in Super Mario Bros. 2D World mode=click see inside button and type yes in question bar Play as Mario=enter Play as Luigi=L+enter Movement=left and right arrow keys or A and D Throw fireballs:Z key Jump=up arrow key,W,or Space Crouch(only when Mario&Luigi are big)=down arrow or S Pause(only while in game)=enter Make sure you give it a heart if you like it.=)
This is Super Mario Bros,but if you press the space bar after you click the green flag you will restart the level you died on with a mushroom,just like Super Mario 3D World. This is also kind of Super Mario 3D World,but its 8-bit and SMB1 levels and 8-bit modern Mario&Luigi.
