This is not a functioning game until you code it! I have all the code in place, just follow the directions in the game! I would start by looking inside the backdrop because that's where it tells you where to find each step. Personally, I think the way I did the tutorial was a little harder for the person following it, but I think you might memorize the steps better because I don't really tell you how to do it, I just tell you what needs to be done.
I hope this works! Tell me if you have any problems! Engine: https://scratch.mit.edu/projects/510262965/ If you use this tutorial, please make sure to credit me! Feel free to advertise as long as it's a scrolling platformer! I can't wait to see what awesome games you make!
