6x7

Fun short level although my finish was different .

Spoiler: Clean finish

with R on the corner draggable adjacent to step, B pushes the final ball. R then steps onto the ball then onto raised vertical draggable. Move horizontal draggable to nudge ball into hole. R steps to winblock

@EL797 - I gave it a go and missed the timing twice on the last ball so just gave up. The shoulder rubbing for the 1st two balls was annoying as B will not redirect the ball when that happens. Had enough. My counting is different than yours as I get 6 x 8.

Small in size but fun challenge...Thanks for sharing @EL797

Good concept, but the execution was lacking. Like @Meko Guy I reached the last step and missed the timing. The close-quarters maneuvering of R and B led to annoying restarts. Would be a good logic puzzle if made large enough for clean movement.

Tricky level
