Is it just me being clueless and missing ... well.... clues? There doesn't seem to be any hint of "what to do next" if the book in the upper right of the main screen has nothing listed. I'm using the Scene Guide that's here as a reference when I get stuck, and it's several game versions out of date, but a number of things on it are events I never saw, however I'm well past the point where they should have shown up. (e.g. Caitlin's "boobjob in her room").
It seems that triggers for events are all over the place, with no logical reason why you have to talk to Girl X at Time Y in Room Z to get something new, and often it's triggered by a menu choice ("Talk", "Hang Out", etc) that at any other time has no new content/text in it. It's getting grindy to "go talk to everyone at every time-slot of every day in the week", but it seems that's the only way to get things to progress. Or am I missing something obvious?
Don't get me wrong, I love this game so far, but if ever a game needed one of Lain's brilliant sandbox-game walkthroughs, this one seems to be a candidate.
