I think that rather than have you doing one action, which is completely random and could make you unfairly lose with one wrong move even if you progressed alot, it would be better if you could have a loop animation where you do an action and you have to quickly stop when you get a notice that the husband is about to check on you.
There was an old game with thsi mechanic where you had to escape from a prison and you had to dig your way and swiftly stops when you saw the arriving guard warning.
Same this but applied to this game would be better and would make it not needed to have manual saves.
Also a gallery of u unlocked illustrations/animations would be cool to see your progress.
