Any chance that there could be some sort of "rare fish" that could be worth large amounts of money (or even experience?) I love catching whales, but something that is exceptionally uncommon could make fishing awesome. (or you could even just make it a hat!)
One nice upgrade would be the ability to buy different types of "bait" for your fishing pole that would increase the likelihood of getting certain types of fish.
Is there any sort of financial reason to be good at school, other than the quests? I never noticed getting any cash while answering the math questions and it would be nice to have some incentive to actually do that. Particularly if the amount you got per questions went up as you increased your combo level. For example, 1 dollar for every q past combo 10, 2 for every q after 20, etc. Same thing with the seal whacking----give us an incentive to get good at these games!
The only thing I dislike is how much luck factors in, in terms of where the bonus seconds are and if you have space to jump before a big or log. That being said, 68728.

You do indeed get money as your combo increases :) same for the seals :D
