How do I save my progress?

To save your progress, go to your profile. You can do this by tapping the icon in the top-left corner of the screen:

In the drop-down menu, select Link email, then No account? Register:

After you enter your email and password, your progress will be saved. We also recommend confirming the email address you used. After registration, a confirmation email will be sent to that address. Simply follow the link in the email to confirm it.
