You need to remix this project and go to backdrops and change the number by 1 every time. So let's say, I made number 1. Whoever remix this project has to change the number 1, to 2 and share it. And whoever remixes the number 2 project has to change it to number 3 and so on. And btw, if you make number 2, you cannot remix it to make number 3. But you can remix it to number 4
