@Yoman that's true, but you forgot to tell that the methods take some time to do: it looks like your program stops for a while. @Yoman take a look at those courses: http://www.greenfoot.org/collections/321 There is a course about the UserInfo class.

You shouldn't save a new score in user info every act cycle, it takes more time than you would think of a normal method. It's better to keep the score in an instance variable, and when the game is over, save it in user info.
