... @Lolita you should make ur level be higher next time. and dont make slider can be reach from whitefloor. Spoiler: shortcut also, so many struggle just to make B arrive at here. you should write down the tricks which are needed.
... 5 stars to appreciate your effort, first time making compact level full of tricks. in before I solved it with shortcuts. then trying to solve it normally, which is difficult yet challenging.
I first had a very quick clean shortcut win, then spent time enjoying the full solution. The highlight for me being the Trick in the hints. Spoiler: Shortcut herd P to the top. Then from same draggable down autopilot and B lands in the warer. Autopilot onto draggable to reach the steps.
Unfortunately - I'm having a very hard time doing the one step auto pilot to get B down to the lower level to get the ball. Is there another way?
I'll go 5 stars but there were some things that I didn't like. First, some moves felt sloppy not clean. The balls had a wedge beside so they didn't rest in the center and B ended up on the rail once getting the lower ball. The rotating motors on the lifts were just difficult, P fell off more than once and did you really need to add them? The level was challenging enough. I did like the auto pilot routes and low ceiling ap. I did see the SBS move but didn't use it since it wasn't part of your trick list.
Agree with @Ray Aznable , there is a huge shortcut. I use claustrophobia, auto pilot, SBS and BB to complete this lvl, really interesting lvl!
