First line of text file - current score user last have
Second line of text file - best score.

Example usage:
ResultsManager.Load(); // load data from file if exists,
// if not init with default values

int curretnScore = ResultsManager.GetCurrentScore();
int bestScore = ResultsManager.GetBestScore();

//Set score - if score is higher than best score - best score will be updated
ResultsManager.SetScore( 100 );
ResultsManager.Save(); // saving data to file
