Good, but needs a bit more

I used to have a version of this game on an old Mac under OS 9, and I loved it. But it had two advantages over this one. It could be set to a larger, full screen board with many more playing pieces on it. And when you cleared a column, all columns to the right of the empty column slid over to the left. That means you had at least a small chance to clear the entire board!
