I like the boat art & the coast animation, and you've got some interesting systems set up. The idea is solid. However, I feel like there's too much time spent going from place to place. It ends up feeling kind of dull. I think the zoomed out camera contributes to this, because it makes the boat animation barely visible. I think zooming in the camera and having it follow the boat would feel much more engaging.
You could also add in some more visuals in the water itself, like small islands, visuals that designate clusters of fish, etc. As it is, I feel like there's no direction to head towards -- you just set out in a random direction, fish, and then return. I'm assuming you're working on this kind of stuff already, since it's in early development.
I also had a hard time telling how the fishing worked -- I didn't initially realize that the fish count went up immediately when you pressed space, so I thought maybe the buoys would somehow catch the fish for you.
The sound effects are drowning out the background music -- I can barely hear it.
