I was making a source-available farm game around the same time that stardew valley came out. Worked on it for about 7 years total mostly on my free time from work. Shortly after SV came out I got a ton of hate from its new fans because I was “stealing from ConcernedApe” and stuff like that. I ended up giving up on the project after a while. And now these days pretty much every rpg has farm mechanics on it.
I don’t know much about rivers but based on the floods we had here in Brazil early this year, I don’t think that house will be there by the end of the century.
