Did I mention that I don't like hidden? After many attempts to get B onto the level past the ball, I hit a hidden ball and that didn't help either. Some times the ball would rest before falling, while others it would fall immediately. Not going to think about it anymore, as I don't play hidden . Here's a huge shortcut that I could see. Spoiler: Shortcut
In the end, the solution is much simpler than I thought. Spoiler I simply pushed all balls and did not worry about the fact that they disappear. After all balls have disappeared, there is a clear path to the win.
