Anyone can make a level by remixing it and simply making a new background. In fact, i would encourage you to so i can add them to my game. (I'm gonna steal em) if you have questions on how the keys work just comment and i will try my best to explain.
a better version of my old game. I credit my teacher for giving me nothing to do and yet encouraging me to code. ps. if you tap the green flag twice it breaks and you have to hit the flag again to fix it.
