are you using points score or coins in your game? you could rig a start scene where you collect one every time you accessed the main menu... hmmm.... but that would just show you how many times you accessed the main menu...
Depending on what scoring your using in your game, points or coins. If your not using one of them, put an action set to the one you want, with zero opacity, at the start scene. In front of character. Then on game over scene have the one you are using set to total. If you are using points and score in game already then I'm not sure of a work around for that. Mainly good for distance based scoring that I'm aware of. Maybe some one knows a way.
