This game is pretty cool, and I actually enjoyed playing it. However, at the start, it was a bit tricky to understand ho-to-play the game, but later on, it was quick to grab the logic. Well, I was unable to find any UI for what fish I have collected or any kind of points that I gathered, which makes the game a bit bland. Other than that, it was quite satisfying to catch fish this way. I would suggest an inventory system to have different sorts of pins, and we can plant multiple pins at once with, of course, some sort of tradeoff. You have to make this game engaging by adding such elements, and I believe it could rise to the top charts if you do so.
I will be looking forward to its development and future projects. Added you to our list!
