Cats appear when you expand past a house/vagrant camp. They have no functionality so far they're just here for aesthetics. i've been no-life-ing the demo since I got it so I can answer some questions :)
Now give me a timestamp where the game says it's okay to drop coins in the river Edit: you know it's probably not a river but either a sea or an ocean seeing as there are independent Islands
@DeathBy Hentai Give me a timestamp where it says it's not okay to drop them in the river edit: You know that rivers connect back to the ocean and it's most likely a river, judging by the art style, environment design, and the fact that you need to sail out past a dock and lighthouse at the end of the island
