Quite a challenge and I don’t think i have won as designed as i never got R to the step between the buildings where R would step onto then off of B. Had nice moves to get R to return to the three wedge steps combo but couldn’t get R climbing. Wasn’t sure if the finish was going to be stable but worked first time.
