The saw is the only way to cut through chains. Cut the rope holding the saw, so that it slices through the chain, and then the candies will swing to the Om Noms.
Cut the furthest right rope, so that saw is released. Once it cuts through the first chain, cut the other rope so that it cuts through the second chain and releasing the other candy to it.
Cut both ropes holding both saws. The bubbles holding the candies with float up to the Om Noms. Do NOT touch the bubbles. If you click on the bubbles they will not float up to the Om Noms.
Release the saw from the first rope, where it will latch on to another rope and cut the chain with the candy on it. Once it is on the second rope cut it, and when it reaches the chain and cuts it, the second candy will be released. Proceed to next level.
Cut the rope on the side so the saw cuts through both chances, and then both candies will fall at the same time.
While the saw is swinging on the rope, cut the rope that is attached the candy. You will have to do time this carefully so that the saw cuts the chain at the perfect moment so that the candy will reach the Om Nom. Once one side is done, complete the same way on the other side.
