Pending mockup with @shashankgroovy

Provide high score persistence via SQLite.

Hi @prakhar1989

I found this app: https://play.google.com/store/apps/details?id=com.logiicsolution.prakharsriv.colorphun on the Google Play Store. This guy just took your source code, added some ads in it and put it on the Store, without warning this is free software...

As you are the owner of the source code, feel free to open a request to google here to remove this copy from the Store, if it's your wish ;)

Don't forget to tell Google that:

• The app is licensed under Apache v2 license and this guy is violating it;
• He is falsely claiming he made the app;
• Provide some screenshots of your own app.

• Prompt username when new score needs to be added
• Persist entered name as defaults
• Use Google play services for better UX
