I like that you can see the number of stars you have much more easily. Sometimes they were blocked by other icons. I don’t like that it takes longer to scroll back to previous levels. I wish there was a way to type in the number of a previous level to navigate to it.
Why have the star system if you don’t want people to try to achieve that? If the goal is to clear the level, then my new idea is to get rid of the stars so people don’t waste their time and get frustrated.
