Nice concept and world building! I love the UI of the book and creatures in particular.
I'm not sure if I missed something, but I was only able to catch one fish (the salmon), and then couldn't seem to find any more after giving it to the Palace character. So, if there is more some further direction could be cool.
If you haven't I would suggest looking into Dredge, which makes fishing fun and varied via simple but different minigames for different types of fish.
A few other small things that came to mind:
- The opening text was hard to read as it was justifying while typing out (so words would move). Make sure the text is fixed while typing so reading is possible.
- The camera felt very close (at least for me, it looks better in your screenshot), so I would suggest pulling it back considerably, and making the boat smaller so it takes up less visual space.
- I would also agree with the other commenter that it was unclear how things would develop. So it could be worth making the hook of the game (pun intended) clearer.
Nice early build with strong design and real character!
Please try out my game if you have the time!
