when you are done with a world, come back and press the next world number button on your keyboard (e.g. when you are done with world 3, you press the 4) if you have any "1-1 but" level ideas, please say them in the comments section below. I worked hard on this, so please have fun! Super Mario Maker 4: https://turbowarp.org/753049043/fullscreen
Thank you to DGR_Dave and the creator 1-1 in SMM2 for giving me the idea. Thank you to google images so I could re-create all the sprites. DGR_Dave has YouTube and Twitch, has a video series on the original 1-1 world on YouTube
