God Save The King

Oh no! The king has been taken and has been thrown into the sea attached to a bomb! Use your harpoon to sever the chain and release the king, letting him float to safety, but be careful not to impale the king or prematurely set off the bomb. You must also be away of the amount of time you have left before the bomb explodes. Gain extra points by hitting stars and by completing the level in good time. Can you save the king?
