The artstyle plus fishing plus talking fish and talks about going crazy made me think it was going to be a indie horror type of game lol. The story is playful and the fish got personality. I really like the showing of the 'fishing bucket' between catches to show that the fish is gone instead of just a text exclamation of "fish is missing".
This is a good idea with a lot of room for expansion if you ever wanted to add to it in the future. Thanks for the game!
