So the game has nothing to do with Summertime Saga. I don't plan on using that kind of system. If a character has to get pregnant in the game, it has to serve the story.
But that's something I'm planning for the end of the game, since there will be too many implications.
Adding money to the game was probably a bad idea, but it doesn't really matter since you can't do much with it—it's not a management game. I'd rather think of a more relevant way to use it.
Once again, the game does not measure relationships in this way, but only through progression in the story, so such a system has no relevance in Goodbye Eternity :)
