Fixes for saved games and the timer. New and restarted games are now saved immediately, so closing the app right afterwards no longer restores your previous puzzle. Completed puzzles no longer reopen with the timer running or keep counting in the background, and the completion celebration no longer replays each time you open a puzzle you've already finished.
