Recent Games List
Another good feature would be a recent games list, like there is on the cryptograms site. That way, if the game score doesn't go through due to some software or internet glitch, we can go back to the game and maintain our success rates. This has sometimes been an issue on the cryptograms site, and will probably eventually become an issue here as well.
I agree that I would like to see the game stats after completing the puzzles.
