I loved a lot about this game! The stardew valley fishing mechanic really sits well with me.
The parallax BG entrance scene, the animated moonlight reflection, and the small touches of lights turning on and off in the city skylines, the clouds floating over the moon (chef's kiss, full marks on visuals).
Having a radio in game is brilliant! I loved the low-fi tunes!
I'm sure if you had time, you would've implemented a fishing log of fishes we caught. And perhaps a visual cue of when the fish bites, for accessibility. But these are just minor QOL suggestions.
Overall, you really nailed the objective of the game; a cozy relaxing experience! Well done!
