Gave this one a go.
I don't know what "ME Volume" is, but it's nice to see many sound channel options.
The girls look cute and thicc, but I feel they look a bit too samey - especially their mouths.
Will rollback be added to the future?
The guide button does nothing (and there should be a 'Return' option there). Also, that menu should come up when pressing Esc.
When this single button is prompted, Space should automatically hit it instead of having to select/hover it first with the mouse.
These narration pieces should have at least some background. The black bg isn't cool.
You should add a button (preferably H) to hide/show the interface.
In general, I think this game has potential. The premise is good and the characters are smart enough to get food and make fire. There's no music, right? Adding some would improve the experience. The bg sounds are good.
Oh, forgot to talk about the sex animation. It's simple, yet well-done.
