i think you can add a death animation and languages
note: im no so good in english, sorry for the gramatical mistakes
when you die, is game over, thats it, but... why you dont add a dead animation?, if you die for the shark, you will see how are going to the bottom of the ocean and see the blood mixing whit the water when your vision goes to black, if you die in the raft, you fall on it and the screen goes to black, but if you die close to a side of the raft, you fell out of the raft and start to float in the ocean and see the sky before the screen goes to black, also add some kind of languages, like spanish and french for people that are not good in english (like me)
thanks for the game, add make it more leght, for laptops like the mine
