Stop the top R from moving by moving the slidable object up. Then use B to push the ball.

Direct R towards the big draggable behind where B spawns. Get R on the stone stairs and B on the draggable under the stairs. Move the draggable that B is on up and R will mount you.

With R on B, you are going to be a bit wobbly. Direct him towards the stone stairs paralell to the stone obelisk, and he will get on the higher part of the draggable. Get on the lower part. R will use B as a block and continue straight. When he goes down the next flight of stairs,

Get R on the metal stair. Bring him down and he will collect star. Bring him back up to continue your journey.

Cool, moderately difficult, logical level! Thank you! I had to think hard and restart the level several times.
R likes to fall off B's head.
And the slider to the first star is badly uncomfortable to grab! Because of this, I restarted several times.
The rest is SUPER!

@Link - Issue number 1: The rail may look like a rounded block but it's not. If you use a flat block like a stone block, then a ball may not roll off properly and since R doesn't stay around long enough, the ball may stop and then it's out of reach. I really hate restarting because the level isn't made stable - a rounded half pillar - ball rolls off everytime.

Spoiler: A bad mount for the ball

Enjoyable straightforward level although I didn’t use the horizontal draggable just above R.

I got it the next time . I didn't use the slider that had the wedge on it nor the slider above the lower R or the metal stairs inside where the lower R is. The lower section felt completely different than the upper part - it's like you ran out of ideas so just filled it in. I also didn't use low ceiling. Overall good level.

Thanks @Meko Guy , @Denis Nazin , and @ridgerunner for P, C, and R.

Didn't use low ceiling and some of the elements in the level. Autopilot B and miss to get the last star on the stone pillar Herded lower R to get the star beside zapper. Same goes to the upper R. Thanks for sharing @Link

Hay varios elementos que estan demás pero me resulto divertido y eso no influyó en mi calificacion. Gracias por compartir

Enjoyed this one and all the forgiveness it had. Was able to make many mistakes and yet solve it without a restart! Fun and interesting level
