I love the fishing mechanic! I find it super unique and immersive and the sonar system and sound effect was very satisfying. The player movement in the town is nice and responsive, and I liked where the story was heading. The art assets and style worked well together, and it felt like a classic pixel top down rpg.
I got confused on how to rest after the first day, there's no bed or anything so I'm going to assume you can't progress after the first day. There's also a bug where if you enter the bar and exit quickly, you get stuck with the interior bar visuals and you gotta walk over to another building to trigger the layer switch back to outdoors.
But overall, great work! I had lots of fun fishing in your game!
