Tried the game for few minutes and noticed something in the UI. There's like a floating V shape Icon on top of the screen and it was continuously moving around which I don't know what was doing unless that's a visual bug.
Shifting from the Lake to the Coast doesn't really feel impactful and the fact that the price for hiring the coast side is progressively getting even more expensive as the Lake upgrade goes up doesn't really make it worth it to spend on. It doesn't really give an exact proportional value for the price that I'm paying it for. The upgrades for the fisherman also lack level indicator and should be included in order to keep track of it
UI wise is just a matter of resolution scaling issue. Clicking to gain some coins also have some soft limitation and doesn't allow me to spam which contradicts typical idle clicker game. Animations certainly do lack and I wish that the fisherman do some basic loop animation not just a static image. Other than that, the game is fine, just need some further improvement
