In its day, MacSokoban -- the version which had the little man pushing around the yellow bags of money, as you heard the shuffling on the floor -- was a great game. Unlike so many brainless games which are available today -- such as Angry Birds -- Sokoban was a brain game. You really had to use your mind, and think ahead, in order to advance from level to level. It involved a lot of strategy. Personally, I was totally addicted to Mac Sokoban, and am happy to say that after a number of weeks, I had mastered all 50 levels . . . at least I think it was 50 levels. This was years ago. It is sad that this current version -- JSokoban -- is PPC only. It would be nice if some talented Mac developer made a modern Intel version, that has the same look and feel as the original Mac Sokoban. Maybe I'll check out the App Store . . . just in case. :)
