One strategy for Under Dwell Level 2, A Close Shave, is to slice the bottom of the middle pillar on a leftward angle first. Release the viking with a long cut going through the top of the pillar and the ice block to the right. Then quickly cut the rope so that he lands on the cannon below. Finally, simply aim your cannon towards the ship to achieve Par. Repeat above strategy, and add an extra cut to release the chest to collect all the coins.
