Currently you achieve a "perfect game" score when hitting the designated number of jellies spread. Occasionally, when you've smashed the board, you manage to convert all candies to your jelly colour. This is a true perfect game but there is no additional points awarded. An improvement would be to give an addition points bonus for such an achievement.
Other thought was it's frustrating when a player disconnects or particularly when a player leaves to stop you achieving the perfect game +2 points. If possible, when a player leaves we could be given the chance to get the perfect game score with our remaining moves.
