This is truly emotive. The image you evoke talking about life while fishing is just breathtaking. I was hooked from the very first moment, although the fishing mecanics made me a bit nervous and I had a hard time trying to get the fish and paying attention to the dialogue. I think dialogue here is essential, it completes the atmosphere and gives meaning to what you're doing. I suggest you give dialogue more priority and importance, and maybe pause dialogue while we're in the fishing task, so we can fully enjoy the nostalgia and love dialogue is creating. I would also love to see which type of fish I have fished ^.^ and how many you need to end the minigame! I felt, too, the final was so abrupt.
Btw music is fascinating and every tiny art detail is great; fishing moving around and the spring breeze atmosphera. Great job. Looking forward to see more!
