Thank you so much for the compliments and the suggestions for improvement!
I originally intended to have more features in the game, such as reasons to keep the fish in your inventory(like a special requests board), and things to buy or unlock with the money you earn, but I'm a pretty newbie dev and it took me quite awhile just to get the basics all working properly, and I just ran out of time. We are considering continuing to work on the game after the jam though, in which case I'll keep your specific suggestions in mind!
