Absolutely gorgeous vibes. I love the music and the art the character design, just how everything comes together. Really really well done. I love how each fish has an element and I can catch them by countering that element with my own, but I was only able to get like 3. I hope I don't sound harsh at all (because the atmosphere and complexity is amazing) but I think there could be an easier way to telegraph which element I should be using.
But overall, I think this is a beautiful little game! The concept of elemental fishing is highly original and fun, and it would be cool to see you expand on this if you so choose. Great work!
