I need to save the score and the stars for each level of my game (the level amount is going to be high, like a match-3 games). Since objects are not big enough for saving this data, and files are slow and other players have to access to the files, i think isn't a good approach.
The important thing here is that if the player is connected to Facebook, for example, you can see the score of your friends somewhere.
Then, which is the best practice to save the levels data for "sharing" with other players?
I think the best should be leaderboards, by statistics, i know the free tier limit (15 statistic names), but forgetting the free tier limits, would be the statistics the best approach for this? Saving a new statistic name for each level.
Thanks in advance!
