"[...] and I think a finished game with 4 or 5 lives remaining will be unbeatable with repetition of last level"(posted 8759 days ago)The point you're missing is that repetition of last level can give player a very high number of remaining lives: check my new Daimakaimura upload, where actual score is 2,224,700 and remaining lives are 30. According to your rule b, my score should be 32,224,700... D'ya think anybody will ever beat that?
