Thanks for sharing @PvB

@PvB Spoiler posted by @BLR is how I complete this level.

Better but I still used tricks and didn't use L. Thanks @PvB
EDIT: I still don't understand what was the point of the slider nearest to B at the start as I didn't use it?

@Blue Tower if you use L bot then the slider must be useful

@Blue Tower Thanks for feedback

@PvB I didn't notice the path to block L but clearly that is for stacking a bot?

@Blue Tower open my spoiler box above and read number 5.

This time I understood your correct sequence. But I can't finish because of the instabilities that you wrote in previous comments
1) the ball in the water is not fixed
2) B may accidentally hit the ball while running past.
3) L may not push the ball near Z.
I tried several times, all these instabilities happened to me. Sorry, maybe I'll try later.
Despite the instability - the level is very cool! Logic Super.
If there were no instabilities, this is definitely a 5!

@Denis Nazin Thanks for playing and your valuable feedback

Had fun figuring this one out but not sure if I did it as intended. B collected all the stars and I didn't use the water ball slider or the slider where B was at the start. I used one AP onto a falling ball.

Solution 1 (BPL intended way)

Spoiler: Vs

Solution 2 ( only B)

Spoiler: Vs

Solution 3 (BP)
