Awesome art, the environnement is well drawn, everything have an animation.
Good music.
I won't repeat Lestavol's feedback about lighting and random pitch SFX, with which I entirely agree.
However, I think the UI doesn't fits well the tone and the colors of the game. I think some changes on the buttons, sliders, and font color would make the UI much better.
I'd say the game looks a bit more Spring-themed (because of the optional color palette I think), but it's okay because fishing still reminds Summer.
Mabye the game was a bit long for a game jam, I still finished one game, but I hadn't the time to make a second one to see what happens if you don't follow the path of friendship.
But the different phases of gameplay chain well. And that was nice too see a game that implements dialogs and a story.
Congrats to your team!
