How do I finish the game if player leaves the screen?

I have a game with a timer and I would like that whenever the person is playing and they leave the screen, the game is over or the timer keeps running.

It's possible?

Thanks!

Add an event where Player is not on screen (select is on screen) and then right click on event and select Invert. A Red X will appear making the statement NOT. Add action: System - Restart Layout. Might have to also add another action Restart or Set Timer to original number.

Thank you very much staleevolution !!

I managed to solve my problem and you helped me a lot!

Every success to you !!!
