Hello. I had shared the link to some friends a while ago. Is there any way that I can disable their access to my game?
I read that I must email to the administrator should I wish to have the game removed/deleted.
I had sent an email but no response yet. Appreciate any advice. Thanks.

Send a private message to me, and I will do it. That said, just occasionally the system fails, and I cannot delete it but 95% of the time it works fine.

As an aside, I get a lot of messages from the site "Contact us" form asking fir games or accounts to be deleted. As these could be from anyone, I ignore them. I will only delete games and/or accounts if requested to do so from a private message from the relevant account.
