Interesting level, thanks! Spoiler I didn't use the draggables... just used autopilot with the descending ball stair by stair...
@chemi That was my intention. But sometimes B jumped 2 steps (instead of 1) and the game could not continue.
@stefanovime also in my case but tapping quickly the right tile while falling made B climb up to the right one.
Very artistic design. Also nice use of the ball in that each time it is close to losing momentum it gets a boost from the small drop.
