I love this type of game, it's so relaxing but also fun to play and progress.
Best part in my opinion is how you can't get fish when it's storming. I think adding a whole lot more events like this that cause other things to happen/not be able to happen would make the game a lot more replayable.
The music is also perfect for the play style and may benefit from other sound effects.
The rewind a day feature could be elaborated on or made more complex somehow, but it is a great start at a cool mechanic.
The art style is what drew me in and I was not disappointed. Nice work!
