Great to see you back. The gameplay looks fairly simple but getting B to move round and not fall off to get the second ball looks very hard and a bit tiresome to repeat. So i have not found the answer to that problem but have won using only one ball.
I have found the answer to moving safely about the roundabout, but feel i am still missing something in this level. The ball to the right on starting never seems to fall where I expect it to land , and I have not found a positive use for the draggable although i can use it to help lower B from the line of steps. I thought the asymmetry of the roundabout was the answer but still no reliable way to get the right ball to fall as desired.
Think i now have the full gameplay. I was on the correct thinking and can now get the right ball to fall properly. Timing was a big factor here. But I will stick to 4* as the mechanism sticking for several seconds every time is annoying.
B was unstable and always fell, so I took advantage of this feature to drop it in the exact place and get the win in two moves.
