Nice job on updating so fast, I do quite like the game! The warning signs still appear for sharks even if they are too small to eat you though. They don't appear for the 'first attack' phase but for every subsequent pass they do.
Also, would it be possible to have a version of controls that doesn't use the mouse? I understand removing the additional 'down' input methods is a way to get rid of the 'faster descent' exploit, but I preferred being able to play entirely with four keys and not using the mouse.
Finally, a question: How many golden fish can you eat before belly size reaches its cap? When I manage to get more than 2 golden fish in a single run, it doesn't seem like the belly gets any bigger than it was after eating the 2nd golden fish.
