Hey,
All your save games are now synchronized across multiple devices!
If you're playing the game from home AND from work, the game will keep all stats/progress synchronized in both places.
Not related, but you may have also noticed some ninja Achievements popping up. Unfortunately you won't be able to "achieve" them until the final game is out. In the meantime you can only behold the beautiful icons :)
Have fun and keep an eye out for the final game next month (exact date to be announced soon!)
PS: cross-platform sync is not yet supported (e.g. Windows - Mac / Linux - Mac etc.)
