How do you destroy only one enemy at a time when you click on them?

hello everyone I am trying to make a game where you click on enemies to destroy them the problem is if you click on more than one enemy at once it will destroy them both I don't want that how do I make it so that only one enemy gets destroyed at a time

If there is no real issue about which one of the overlapped enemies is destroyed you could use enemy > pick top to choose the enemy highest in Z order and delete that first.

thanks, brother worked like a charm
