I did not finish testing this level, but it looks like you might be onto something. My intention, was to provide an over-or-under possibility, but I havent had any luck dragging it down below either. We'll give it a few days, and then ill make it easier to grab, and keep the goal location the same.
Heres another thought. It opens the opportunity for the yellow dynamic to be used for the final propulsion into the goal. That Blue rod can be tweaked (shortened) to slow the movement to the left down a little. How the goal piece gets its final boost is beyond me at this point, but i thought I would share anyhow.
levels like this (and the two in the collab forum) are a perfect example of some of the limitations in unconnected solves. Not that im skeptical that it cant be done, but commenting on the fact that everyone just gives up when its too hard :-)
I think youre probably onto a better idea there, I tried working on some similar timing last night, but couldnt get the brown rods to fall "after" the ball went through.... see some of my other attempts above for action, I think we can get this.
