Good game! But I think it needs to explain the mechanic a bit better on the first catch.
It may not be obvious to people how to catch the fish, it took me a little to understand it myself.
The atmosphere is great, the style is amazing and the story is eerie, I enjoyed it a lot, but I can see that people could have potential issues seeing as the game does not explain controls / how the mechanic works.
Even just a explanation on the ItchIo page would do to clear up potential confusion
But other than that, I enjoyed it a lot!
