Hi, I recently purchased Sparsha's Firebase plugin, and wanted to do something very similar.
So I asked him if it is possible, he said, yes but not directly (he didn't share more details).
I would contact him when I reach that point if I am unable to set up.. But my guess is it would be done using Date/Time plugin (locally) and instead of the regular "Scores" (or Level) database, have new Day1, Day2, .... Day923 databases everyday to store and display that day's score.
Again, I haven't tried it yet. But yes, I'm sure it is possible.
