What's New in nonna
0.5.1
October 29, 2026
A new sky over the Yard. Clouds drift by, birds pass, green hills roll behind the fence and flowers have come up in the grass. Your cats react now: sparkles when they catch the feather, little Zs when they nap, a heart when you tap them, a puff of surprise from the tunnel. Cats are rarer, and that makes each one count. The first round your child ever wins brings a cat home, and after that a new cat arrives every second time they level up, in any world. No cat you already have goes anywhere. The Yard shows twelve cats at a time and they take turns, so every cat gets its day out and the garden never gets crowded. The counter still shows how many cats you have. Progress is kept the moment a round is won. Going Home while the cats celebrate no longer loses the round. Small fixes throughout.
