I don't know how to fix the camera thing in battle, but I did fix the incorrect teleport in the city and made the main character a little bit stronger for the early game so that he doesn't depend just on Chestnuts to level up. The one about the lake is, indeed, not a bug, it's just funny.
I'm really glad that you like the game's aesthetics! This is a very simple game and, being more a game artist than a developer, it makes me happy to see my players like my designs. I hope you enjoy the rest of your playthrough.
