Yeah! In the latest version it prompts a save when you go to bed, actually! But I feel that as long as the game isn't stable and relatively bug free, its best to let people save anywhere and have autosave for the time being, if only to help them keep their sanity a little bit as the game falls apart in their hands. But yeah, once this is closer to being all finished, I will probably shift to saving only upon sleeping, that would be the most appropriate to the games overall pacing I think.
