This is an entry for @astnmc 's intro competition. ( https://scratch.mit.edu/projects/396704502 ) The cat is not part of the intro, look at the code for it to see why it is there.
To put this intro into your project, backpack the Intro sprite and the first backdrop and take them out again. For any code for the project, put When green flag clicked, hide and when I receive message 1, (what is going to happen in your project). I hope you like it! By the way, if you don't like the music, you can delete the old one, put the new one in and label it Intro. Everything else is automatic. I don't know how to get new music so I stuck with that music.
