I think this game could benefit from a sign that an event is over and that the day has changed. I have been playing for a couple of hours and the narrative suggests that I have been playing for several in-game days but it feels like one long day where I had breakfast a bunch of times. This is not the sort of game where there would be a day counter; and I think that would detract from it really. However maybe after an event has ended, There would be a simple animation of the sun setting and rising. Real quick, for like two seconds. Then we would re-appear in our bedroom. No text, or anything to read. Something simple and easy to digest without distracting.
Missing dates could be a real issue like seth's for instance. I think that having to manage the clock would be a great idea
