PTGames I found something of a continuity bug. I talked to the sister in her bedroom and one of the options was "talk about what happened" and the first line was about a kiss but I haven't done something like that. I backed out immediately since it felt like it triggered before it should've, so it might be talking about their past but the phrasing of it makes it sound like that's not the case. The hint I have for her is to check out the bathroom, but she never shows up there anymore after I saw her once, and that time the main character was disappointed that he arrived too late to see anything.
Edit: for claraification I'm on Mac.
