you can still make it so, when the ball is attached to the paddle and the paddle is moved, the ball would move together with the paddle

I was commenting on menu already (it’s the tela variable)

in this sketch:

click mouse in menu and click **ESC** during game

(similar to function menu() put the game stuff from draw into a new function `playGame()`, so your draw() is nice and lean)

our goal here is:

ball is already attached

we move the paddle

ball moves with the paddle

which keys are involved?

No. Or as you like it.

when the attached ball is moving with paddle it looks better.

And you can decide where you throw the ball by moving the ball prior to sending it again

i had an idea  
scrap right paddle holding the ball make it so only the left one holds and and put a breakout like like behind the right paddle making it a mix between pong and breakout.

the left paddle is an attacker while the right one is a defender
