It think a way to see the pictures full-screen again could be beneficial. When you see them the first time, there's no indication you'll have to sort them, and it can be easy to not pay full attention to them. Too confusing to try to make out and order them with the sprites, I haven't been able to do it yet. If there's no recent save, it could mean quite the backtrack.
For me, Lindsay went off with Stu in that room. Is it always just going to be one person, or is this because Lindsay is 'ahead' of the others and if they would all be tied for Stewart affection they'd all be involved (if only voyeuristic)?
