have a problem with End game

I have the “last man standing wins” option, but why does the game end completely and have to be restarted when all the players leave and only one player remains? I want to continue the rounds and I don’t want the whole game to end, even if only one player remains.

I want the rounds to continue, unless the last player is leaved , in which case the whole game ends, not just the rounds but the whole game.
