Your project is not a beginner project.

In your intro the “two player” sprite can be simplified AND you can save CPU

Split the “big” green flag into one with hte “move” alone and the other with this:

when this sprite clicked
broadcast [show v]
broadcast [two players v]

Do the same for the sprite “start”

when this sprite clicked
wait (0.1) secs
switch costume to [... v]
wait (0.1) secs
switch costume to [... v]
wait (1) secs
broadcast [show v]
broadcast [com v]
hide

In the sprite of the ball you can regroup the “if … then …” one after the other in the same “forever”.
