Interesting level. Some complexities only show up after I tried to improve my speed. For the most part, those moving about just serves as time delay, but don't seem to provide anything but distraction. A good first submission.
Hi and welcome...well,the design is nice,the intended path(to be your first level)is nice too BUT the FD (free draggable)is a dangerous element... Thanks for sharing @Brin41k
My 1st win was with the Free Draggable (FD) that you left not anchored with a slider to push B off the level onto the surface. I simply moved the FD, over to the lift above where B started and dragged it to the win block. My 2nd win was probably as intended. Thanks for sharing your 1st level.
