Same problem here. I completed all levels. When I tried to play again using a harder level of difficulty, it would not register my score. It seems as though ONLY the very first player's score is recorded. You can't even beat that score because it won't keep current score either. Anyone else with this problem? I really like marbles (chess is too hard -- even at easiest setting). After playing at easier levels I wanted to challenge myself at harder levels, but keeping score makes would make that more interesting.
