Ok, the game seems interesting, but I can't rollback, and more importantly I can't save. And I don't mean I can't use old saves, to be clear, I mean I can't work out how to save. The usual Renpy stuff isn't working.
Hmmm, not sure what to tell you, maybe your version is faulty? It's definitely working, no one else has said anything about not being able to save or usual renpy stuff.
I never thought to try it at first since usually for Renpy games I just right-click, or usean in-game shortcut. Like how you put settings on the phone. That was what I meant by 'usual Renpy stuff'.
