The option to log in using Facebook is temporarily limited (starting on the 21st of January 2022). The other methods to link and recover your account as still available (Google Play Games, Apple Game Center, Sign in with Apple, or using your email address) as usual.
If your account is connected only to Facebook, you can attach your email address or the other login methods at any time. Go to "Options - Player menu" and use one of the available login methods so that you always have an option to recover it.
If you need to recover your account connected only to Facebook, get in touch with us at https://www.madfingergames.com/help, and we will help you out.
We apologize for any inconvenience this may cause, and we will inform you when the Facebook login option is available again.
Fight hard, party harder!
