Loved it! The concept, art, sound, and general execution were all great! The only constructive feedback I can really give is that it probably needs some balancing. Once you get the knife, you're able to just kill all the big blue fish and buy everything in a day or two. Then, fully kitted out, you still get wrecked by the group of sharks. There should be some stuff that takes a couple more days to farm for that totally destroys the shark (like an Iron Man suit or grenades).
