Great level Karl! For a partial solution, (after the ball drops) try drawing a line starting from the far right wall, straight across the tops of the upper round objects and out the opening a little, then up almost to the top of the screen, and then VERY FAST over to the right side of the screen. The end result will be a rectangular C shape that you can then drop a big object onto (over near the right end of it) to get rid of several of the round objects. I'll leave the rest to you, but I wanted you to know about that "super fast/super length" trick with lines. It's very helpful sometimes.
