Question

I want to use firebase as backend to store player’s game state and I would like to know that authentication/ log-in is required for this game or not to store game state when integrating with Firebase. I also use Dialogic to implement the visual novel game. Inside visual novel game, there will be 3-4 mini games for a player to collect papers, find a box, plant a tree, Thanks for your responses :grinning: :grinning:
