Super interesting idea! The concept is a fish just swimming around and eating not just fisherman, but the entire BOAT was pretty funny when I first saw it. I also had a laugh after understanding the name of your game.
Probably just a skill issue, but I found it super annoying when hooks came flying at me from off screen, since I wouldn't be able to see the boat for the hook cue. I think widening the view, reducing the hook speed or reducing the range of those hooks would make for a better experience. A couple other small things like being able to see past the water on the borders make the game feel a little unpolished, but that's just the 48hour game jam experience haha.
In all, it was an enjoyable game and a really cool demo :>
