• Redesigned achievements screen: Stats and achievements now fit neatly into the screen area and scroll independently of each other, so your progress and gem rewards stay easy to follow. • Reworked interactive tutorial: A four-step guide shows you how to buy cats and merge two identical cats into a stronger one. Highlighted buttons and marked cats point the way, and the battle waits until you're ready. You can restart the guide at any time from Settings.
