That was fun! The finishing minigame was nice and cozy, and the logbook was a great way to add some replayability. I actually clicked on it before reading the tutorial after finishing the first day, as I was very curious. XD
I really like the little details, like the leaves falling off the trees as the days went by and the catch feedback, especially when it was a new discovery or special catch. The way the passage of time was portrayed was really well done too, with Oct 31 being my favorite. The pixel art in general looked great!
One thing I was curious about was how you decided on the difficulty of each catch. Were the smaller zones on the bars tied to rarer fish or new discoveries, or was it just random?
Nice job on this!
