Wow, this game is awesome!!!
You can tell the amount of effort put into every detail of the game! I especially liked the small detail that the fish in the water were the actual fish I was catching, not just decoration.
The only minor nitpicky thing I can think of to improve is to make the fish you would catch more predictable. I kept trying to strategically cast my hook to target the bigger fish but they'd suddenly change directions or sometimes go through the hook...
Overall, it's an amazing game and I love how it turned out. Great job :)
