Haha, I actually called the square bracket (the one with the point in the center) the "evil block" while I was working on it. I think it'd be a little easier to deal with if the marble didn't go flying off to the side so easily. If I did any more work on this game, I think the first thing I'd do is experiment with the mass of the marble and perhaps a speed limit on how fast the rows can move, to make the game less punishing. Thanks for the feedback!
