SUBSTITUTE LESSON 4: Super Mario Bros. 

Try to recreate Super Mario Bros level one in GameLab.  You can use question blocks (with coins or mushrooms) or goombas (bad guys). Remix your previous GameLab game and replace sprites/scenery with appropriate backgrounds and sprites. You may use the sprites I've given you here, or different characters from GameLab / elsewhere.
