Hi,
I would like to add fierbase SDK in your game as I do have extensive experience in mobile game development for both android and iOS.
I have solely developed 100+ games and already worked on Firebase Crashanalytics and Performance functions for android platform.
Having developed similar games before, I understand most of the requirements, but it would be great to discuss the game further, in case you want something much more specific.
I am looking forward to working with you.
Thank You
AM
