If not mobile then put your mouse in the game and where you drag the mouse the paddle will go there and if your mobile then press and hold and while pressing anywhere and holding move your finger right or left and then the paddle will follow you and if you press the flay and the game does not start then press the flag like about 3 4 or 5 times and it will work bye.
I made this so scratch beginners can remix or look inside the project to copy one by one.
