Just Right

It's been a while since my first three levels but I'm back with this have fun

Strange level cause I do not know if I enjoyed the full & intended gameplay...

Spoiler

at first,when I did not know that B was in the level & had a purpose I get the win using R but missed the other star...then,when I realized that
B was here too,I used him to move the platform & used R only to push the ball... the vibration did the rest & the ball touched the star & the win

thanks for sharing @Gaetan

@delator77 thanks for playing. I appreciate the rating too

I did the same as @delator77 to win using just R. I think there is a lot more to this level using B but I couldn't figure it out.

Interesting but not satisfying as it is difficult to know if gameplay is intended. Didn’t use the end draggable and only slid the side draggable in and left it there.
