Kakuro Blend now uses Steam's Auto-Cloud configuration. This means that once the game data is saved within the game, and you exit the game, Steam will automatically save that data to their cloud. So whenever I update the actual content of the game or something bad happens Steam will have a backup.
If anyone has issues with is and it is no working how it is supposed to work, please contact me so I can work it out and get everything back the way it should be.
