This update is very important, though it does make the game much less fun right now. This commit removes all traces (hopefully) of using spears to kill sharks. Sharks are one of the most important species in the planet and they are being killed off at an alarming rate. It is hard to gain sympathy for sharks because of their presentation in media as dangerous people eaters, top killers on the permanent hunt for our blood who must be killed at any cost. The truth is that they are scared of humans and think we don't taste good at all! I cannot in good conscious have my game keep propagating this negative image and as such would rather have it broken than harming the environment.
