Welcome to the Jelly Community! Feel free to check things out and I hope you find this place a great way of knowing other players and engaging with them as well .
That said, our levels change and adapt as we reiterate them to make them challenging and more entertaining. That's why you might have seen some with 35 moves and now you are facing it with 12. But don't worry though, the number of moves is also connected to the chances of making more special candies and combinations. So now, although you have less moves, which makes it more strategic, you also have the chances of aiming for bigger explosions!
I hope that made sense and gave you a better understanding of how it goes.
