Funny concept that fits the theme, and I love the art style! It has that edgy Newgrounds kind of look to it. I didn't have a whole lot of fun with the gameplay, though, and there were a few quirks. First, after filling the Captain's rum bar once, it doesn't seem like you need to do it anymore. It gets topped off automatically. Second, in this level there appears to be two dig spots, but there's no win condition? I wrapped around the island several times, even restarted thinking I broke something, but nope, it's two things to dig up and the game just continues running. I would have liked some sort of indication that the player won (or a checklist of stuff you need to do if there is actually more stuff to do).
You mention in the page something about this being one level out of the whole game. Are you guys developing this as a full game? If so, congrats! I hope this feedback helps you improve, and I hope the game keeps its whacky style.
