What latest version do you mean?
The last 0.5 version is out for the public and here.
You said that you haven't played the game yet, but still, arguing about the purposes of the bad endings? I don't think it's fair without the context. Try to play the game and then tell if you need to farm points or not. Or don't play it, then why argue about something you don't care about in the first place?
In my eyes purpose of currently existing bad ends are to close ways of where the story won't go.
There are two bad endings in MurMur. The first one is if you decided to reject all of the girls. I'm assuming the player would do that if they didn't like the girls to begin with, but there is no game left to play in that case. The plot is tied to all the girls.
The second bad ending is tied up to Shinigami as she is the main plot device. If you haven't earned enough corruption points then you basically didn't do what the deity controlling your life said you to do. And as logical as that, if you haven't been on the good side of her, why would she care even? I don't feel like scripting hours of gameplay just for you to fix relations with her. You had a chance before.
On another hand I've admitted before that I set the bar of the points you needed a bit too high, so I will lower it. Besides that, there are three other options of how this scene can end.
And also I'm always open to suggestions of how to better up my game.
But only to constructive ones.
