Of course, every game needs some precariously-placed barrels, and AarrrRL is no exception. One of my must have "extra piratey" features are exploding barrels of gunpowder.
You can also lift barrels by walking into them, and then lower them elsewhere. Eventually I'll have some way of puncturing the barrels so that you can leave a trail of gunpowder and create insane traps. Avast!!!!
