• Clearer board colors: deep jewel colors that are much easier to tell apart, now with a ruby red. • A cleaner board with square cells, just like the board on the home screen. • Level complete now shows your stars right at the top. • Light Mode looks better: the cards stand out clearly from the background. • Notifications are now asked only once. • Small design improvements and fixes.
