I'm curious if the game just goes on forever and all you do is survive or is there a final mission?

Oh, thank you. Now I can sleep easy.

I dont know whats wrong, I know my average score should be about 9.3 yet on my page it says 8.2! Whats wrong with this? I scored my games yesterday and it still says 8.2, ive evenscored some more from my nintendo days and still said 8.2 Help me figure this out please.
