Use the crab near the bottom right door. Before the final jump, freeze the crab high enough on the right wall that it can be lured up to the flat platform. Perform the final jump as it is unfreezing so it starts moving upward. Then go to the lower ground a bit to the right, jump and aim down to lower the camera to lure the crab. Note: The hardest part of this climb is the pixel precision when jumping around a ledge. Too many pixels: left is a fall, right you clip through the crab, low you miss the jump and fall, high is a bonk or crab clip.
