Green Flag to create the level and click it again to make a new one. Control Mario with the arrow keys (he was just handy in my backpack and that's why I chose him). You can also go to the edge of a level to make a new one. This was my first real shot at stamping sprites, so let me know what you think and what I could improve in the comments.
Guys I made this into a game please check it out! https://scratch.mit.edu/projects/63979818/ The fire is from ShockTheHedgehog and Mario isn't mine, but other art is by me! All scripts are by me, and I even managed to make the island creator in just one script. By the way I'm turning this into a game! Hope to have it out soon!
