You sure you uploaded the right version? I only see 1 type of fish, no power-ups at all, and the shark never leaves. Just a heads up :-)
Menu and pause are nice though, as well as removing the damn whirlpools.

At first I thought they might come later, but still no other fish, or power ups. Nothing! I manage to get +1000 points, but still no other fish. Just the small ones. I tried the demo version just to make sure the update didn't get mixed up with that one. The demo version only allows you to play just a little bit, because the shark follows you and eats you no matter what, even if you try to avoid it! Nice job on that one, so people will want to buy the full version.
