So I just encountered something through play that was likely not intended when implimenting the feature, but it was kind of amazing.
I was working on getting a wall set up around this village I'm setting about making safe (functional walls, so awesome). The internals were not all lit up yet and I heard a skeleton walking around nearby, so I turn around and see it walk out at me from the door in this picture:
I had planted all the pumpkins here to have a steady supply of some kind of food for Hardcore Hunger and at the time only the nearest one was grown. Not being much for charging skeletons, I did the logical thing and jumped behind the pumpkin for cover. Then suddenly TWANG, POMP! The pumpkin exploded into seeds and my perfect spot of cover was gone. It took me a moment to process that the arrow the skeleton had shot hit the pumpkin and popped it.
That's right people, Hardcore Melons also gave us destructible cover.
