Absolutely nailed the audio! And your game uses the theme very well.
To be completely honest, at first I was a bit put off by the screenshots, but it didn't take long for the art style to grow on me after opening the game. It really adds to the game's atmosphere.
The only thing that would have made this better is if items were sold faster once you reel the hook in.
Really impressive that this was made entirely by one person in a week.
Please do more game jams.
