* Previously, only the best score was remembered.
* Now all your high scores are recorded, as are all the words you've ever found.
* View your best scores by touching the high score on the main menu.

Added Danish translation (thanks comradekingu), and updated many other translations (thanks to the wonderful community of translators).
