CUBICLE CRUCIBLE

Fantastically COOL design! Absolutely every interior detail is thought out, and I thoroughly enjoyed looking at it. Of course, the water is a super cool idea!
The gameplay was also very interesting. I had a blast exploring the interior and its details.
For some reason I spent a VERY long time looking for one of the stars. You placed it well!
At the end, I missed the star in the trash can, but the Office chair on wheels helped me. I pushed the trash can with it, and B finished.
AWESOME, of course, a 5!!

By the way, I won fairly and collected all the stars with B's help!!
But using your office chair can significantly shorten the journey! 3 stars can easily be obtained with the chair. I really respect the design, so I didn't use the chair—I just enjoyed it visually. But be careful with such flying objects in the future.

I liked the steaming mug of coffee. I also used the chair but i think that my gameplay is different from that of @Denis Nazin . My B captured all of the stars.

I got all star, except one
But went on white floor
And net basket Star is missing
Can't get up on platform / desk

Super cool design & a fun gameplay. I took all the stars with B & I did not use the chair at all. Thanks @FUNATIC

Spoiler

Once in the white space, it's relatively easy to climb back up using the rotor. In my experience, B starts rolling, propelled by the rotor, and during one of the turns, without doing anything, B gently lands on the stairs at the top. And so B is ready to grab the last star, which is in the bin. I got it by pushing B with the draggable that's next to B when the level opens. But it took me a few tries...
