We noticed that your app uses Google login for authentication purposes but does not include account-based features offered by that site.
In order to use Google for authentication, your app must include significant account-specific functionality from Google.

Next Steps
Please revise your app to implement your own authentication mechanism, or incorporate significant account-specific functionality from Google.
If your app does include additional account-specific features from Google, please provide us with details on where we can locate these features in your app.

Legal - 5.1.1
We noticed that your app requires users to register with personal information to access non account-based features. Apps cannot require user registration prior to allowing access to app content and features that are not associated specifically to the user.
Specifically, your app requires login on launch in order to start playing.
Next Steps
User registration that requires the sharing of personal information must be optional or tied to account-specific functionality. Additionally, the requested information must be relevant to the features.
