I like the game idea and love how going deeper and deeper you explore new species of fishes. Try adjusting the "Collect" button at the end. I do have few suggestions to make the experience more interesting. Although I love the display picture of the game, I haven't been able to play it yet because of the game compressed as a .rar (I don't have a winrar). That's a slight inconvenience and my feedback would be to always compress your games as .zip. I will however give a proper feedback when I play it later!
