“The long wait for the surveys is now over and we are happy to announce that surveys begin today.
You will receive an email from Fangamer at the email address you have registered with Kickstarter for Kickstarter backers, or either your PayPal or Shenmue.link registered email for Slacker Backers. The email contains a link to your survey with the questions needed for your rewards. Here you will confirm your preferred game platform and other rewards, write your guestbook message, credit name etc., and get to us all of your info that will be in the game and to get ready for release and delivery!”
