I still do not have received the free coins.. what is going on are you joking with people?
Give them some time. They're dealing with a lot of users, you will receive your free coins. I suggest you PM the dev if you haven't already. If you have, I suggest waiting another day or two for a response as I imagine they're busy working on a backlog of users' messages requesting updates/free coins.
I received 2 days ago the mail and have sent my walletaddress. But still not received coins.
