I wanted to try this game out after hearing about it from a friend. I downloaded it and have tried several times to get a verification code sent so I can log in and play, but no matter what I try, I can’t get the email to send with the code. I have tried using different emails, I searched All Mail and Spam… not sure why I can’t receive the activation code email. 
Hey there,
We’re unfortunately experiencing some issues with the verification email system at the moment. We’re looking into the issue right now, and I’ll be sure to reply to this post to let you know when it is fixed!
Sorry for the inconvenience :(
Update: I have been told the verification email issue is now fixed! Please let me know if your issues persist.
