The two upgrades we added to this second version of the game are simple, yet they add a lot of value to the game. We added a persistent high score engine, so users can actually keep track of their latest record, and have a sticky record of past successes. We also added a pretty nifty feature that takes a snapshot of the game board each time the player scores, as well as whenever the player ultimately dies out. Once the player dies, we display all of the snapshots we had collected throughout the game, allowing the player to save those images, and possibly share it with his or her friends.
The first thing you probably noticed about the previous version of this game was that we had a placeholder for a high score, but that number never changed. Now that we know how to persist data, we can very easily take advantage of this, and persist a player's high score through various games. In a more realistic scenario, we'd probably send the high score data to a backend server...
