I personally think it was a good idea to try and submit this. The gameplay is nice, and the message is smart. I respect what you're trying to do here, and I hope the game does make a difference, even if not everyone on newgrounds cares, or not.
P.S. I have an idea for one of the updates. Is there any way you can incorperate spending your conserve points between weeks on upgrades? like making the dolphins faster, or smart enough to automatically swim away from nets or fisherman boats? This could help improve the gameplay a bit more, and make the game more attractive.
