For the first time you now control Ro's child.
Here you need to pull down the inner building using the holes as your pull down point, twist and join them together again until you can create the exit path.
Next you have three monuments, it is the same idea, twisting to find the different routes.
First twist the building that Ro's child is in the reveal the green door, send her through it and she will come out of the other green door, direct her onto the pink square.
The pathway changes on the bottom monument, go back through the green door, then through the yellow door and you should now be on the bottom monument, stand on the circle, now the bottom part of this monument is rotatable, rotating it moves bricks on the top monument which will allow you to go through the pink door then through the middle door in the top monument and Ro's child will be reunited with her mother.
This next section is a bit tricky you need to separate these monuments by sliding down on the yellow circles. You will need to twist to reach the pink square on the bottom monument. A staircase will appear when you do this. Go up is, rejoin the monuments and twist them until you can go out the door to the right of the top monument.
Here you need to use the yellow blocks to get to the first doorway. Step on the green square, this will give you the yellow blocks again on the top monument, go through the door and you will get to the top monument, you need to twist until you can get to the red square, step on it, then go back to the yellow square to get the green bridge on the top monument, go back there again, twist and find the new exist to the right.
Here go to one end of the shape, twist it and go to another end and twist again. Really hard to explain, but if you have trouble, please see the accompanying video.
The next part, head towards the square, use the yellow circles to split the hidden monument until you can walk onto the next target marker, walk onto it when you can.
Another hidden area is revealed, so slide the yellow circles again and head for the top red marker and black star. You'll need to make a star by making fast circles with your finger above the monument. This completes the level.
