I'm so glad I finally got the chance to try this out! I love that you took the time to create multiple quests to motivate the player to keep fishing, and I think your world is really sweet. Your character design is fantastic.
I do wish there was a little bit more guidance to explore the small settlement and talk to the various inhabitants. I happened to wander over and talk to everyone, but it wasn't immediately clear to me that there were that many characters to talk to and it's easy to miss some of them entirely.
I think your fishing mechanic is super interesting, one of the most involved I've seen. I found it a bit frustrating, since it seems like no matter what I do the line almost always snaps. I think that's just an issue of practice on my end though, and I think you did a good job of making the mechanic feel unique to this game. I plan on going back and spending more time with it.
Great job to the team, this is a really polished experience and it's clear that there was a lot of love and work put into this!
