Greetings from Wonder People!
You can change your name by simply tapping your display picture in your profile menu. It will prompt you to edit your name. Also, you can use your own name by connecting your game account to Facebook. Once connected, your profile name will be displayed on the game. Please be advised, if you have already connected your game account to a Facebook, you cannot change your name anymore.
If you have any more inquiries and/or feedback, please let us know. Thank you.
