Amazon's going over a variety of new software enhancements for the Kindle Fire HD, and one of those new features is Whispersync for Games. The company says it'll keep you from ever having to start over, and it stores any levels you've unlocked. It sounds like that this is for syncing gameplay across multiple Kindle Fire devices — though we're not sure how many people out there are playing the same game across multiple devices.

There's also a new Game Center-esque leaderboard, showing your social rank, achievements, and overall progress through the title. It's not entirely clear how social rank is determined, but we're not surprised to see Amazon try and make games a more social experience.
