You probably aren't doing anything wrong. A lot of the time slots are currently filled with repeatable scenes that just affect your sanity level.
One of the more easy to miss sections would be the library archives, which only open on Mondays, Wednesdays, and Fridays from the library atrium.
Other than that, a couple scenes are locked behind your prologue choices.
It's becoming clear to me how important a scene finding system is. I'll make that the priority after I finish what is currently planned for build 0.5.
Thanks for playing and for your feedback.
