I have already tried to save all and reset them when user enters main menu, but I also have 3 variables which must work during hole game and I can't reset them. When I want to load attributes in order to use 2 relevant variables, it loads its previous values, so another three variables don't work properly. Anyway, I think that maybe I should try AS3 as Roadcat recommended.
Thanks a lot.
And one more question:
If I want to create a leaderboard and use it in my game without any mochi or congregate servers, will it be useful and proper thing to show people from different countries their scores saving them only in my game?
