The 'autosave only' mode is an interesting idea, but it's probably not practical, from a reliablity standpoint.
I just noticed that my game isn't autosaving anymore. I don't know why, or when it stopped, but the 'game time' counter on the autosave slot isn't going up any more, and since there's no way to hard-save to get around that, i think I'm going to lose a shit-ton of progress with no way to stop it.
Please add a the very least a debug-item or something in a menu somewhere, which can be used to enable manual saves.
Edit: Also, is it intentional that there's no way to escape from sex-moves? Being trapped in a handjob doesn't make a lot of sense to me. Literally just let go. lol.
