1. Add everything to your project. 2. Add the costumes you want to the changing image, and change the costume in the Credits sprite to match your credits. 3. Change the repeat until (21) block in the credits sprite to the sprite's y variable when it's stuck at the top of the screen. 4. Hide the y position variable. 5. Change the back button to go back to your project. 6. Add music. (optional) Not so easy to implement, sorry about that. ST, how about a Project-in-Project feature? :)
Changing image sample costumes by the ST.
