I got ending B!
I'll be honest, I kind of had to force myself to keep fishing. I was able to power through it, but it was rough. (but don't worry, people say the same thing about the spawn rates in my game!). Maybe add an option to 'sleep' and skip a few hours, or a slightly longer fish time equals more time passes?
Overall I like the idea, and the story was nice. Was this a sequel? It felt like we started in the middle of a story instead of the beginning.
