Such a nice game! I really enjoyed the art style and maybe some music would've added to the atmosphere :D Other than that I enjoyed it a lot and I spent way too long finding that last fish hahah.
I don't know if you've heard of Game Development World Championship before (gdwc2019) but it's a competition for indie game developers where they can submit their games and it's free! It's great if you want some more visibility for the game and it only takes a couple of minutes to join :)
