Hi! I love this game so much it took me about an hour so definitely kept me busy, I don't think I've done it right but I have a feeling I'm close.
The part I'm most stuck on is which way around Richard and Junior are. In the cassette tape Richard uses Dorothy's name and junior's name which is kind of odd If it was his Mother and Father but he is talking about "girls" so I assumed it was his daughters. However now that I'm writing this I've realised he could be talking about his Granddaughters and wanting a grandson. But then Lisa mentions her husband being self-centred, which Richard seems to be as he wants his family name to continue and we don't hear anything from Junior which seems wrong if he's self-centred in that he would want to talk about himself a lot.
This is by far my favourite game I've played on itch so far!
