This game seems really fun, the art is great, I love the music and sound design, but I could not really give it a try because for me there were simply not fish spawning.
I loved the fisherman and the different levels, they looked really great, but no matter what level I went to, it was just the empty water without any fish, so sadly I cant really say much - I hope that this was an issue on my end and that others can give it a try as this game seemed really promising.
I could tell that a lot of effort went into this, so well done regardless! :)
