Start the Scratch project, by clicking on the green flag. After clicking on the green flag, the orange Scratch cat will start to move 10 steps, and then move -10 steps, also known as forward, then backwards. In between each steps in motion, a sound will play for 0.25 beats. Later on in the project, you can click the space bar to change the orange Scratch cat's color effect by 25. Every time the space bar is clicked, it will change the color of the orange Scratch cat by an effect of 25 and play the sound of a cat, meow.
I made this project by following the Scratch tutorial, and completing the steps as asked. I made the project by myself, learning about scratch along the way. I used all my sprites and backgrounds from the library, made by the Scratch team.
