Have captured all the stars but I am sure that my use of the balls is not the designed way as one ended on the White and I used one three times. Will try to find a better solution later. In Mallorca this week.
Very nice level. Spoiler the biggest headache was how to put B in the final area & although I thought in something similar you did I didn't see how to do so I had to find another way. And I did.A subtle push to B with the draggable in front of the fence & the double stairs. This time not a shortcut, only another logic step thanks @Meko Guy
@Meko Guy.. Thanks. I came back to the level and this time found the designed gameplay. Very enjoyable awkward moves. In my first win I didn't need to use the corner ball with two stars above because of an R move that let R take both these stars simultaneously. Spoiler: R move
