This is my first scrolling project, and I am laughing my head off (I'm not actually laughing, but if I was I'd be laughing my head off) at how easy it is to make a mouse-controlled scrolling project 4 times the stage without any variables, and the same single-line script with 2 equations in each sprite. If you want to see how i did it, then download the project, select one of the sprites, go to the scratch paint editor, and click on 'set rotational axis'. Or just ask me in a comment.
