Brainstorm the main features (stats tracking, data visualizations, achievements, etc.) of game client

Think about the data that you want to save in Firestore and what will be doable based on that.

I've done some work on this, but I don't think I want to mark it complete. Here are a few ideas that I have:

• Basic counting stats (puzzles solved, cumulative puzzle time)
• "Best" stats (fastest puzzle solve time, what else?)
• Completed PuzzleGroups - are these saved as achievements?
• Consecutive daily puzzle solve streak - I like this one a lot; it's just kind of cribbing the Github commit frequency graph. Shouldn't be too hard
• Anything else?
