Is there any possibility you'd be willing to facilitate a player playing as a member of the faculty? Nothing perverse, before people get that impression. I can send you a rough idea of my character if you're not sure.
I'm 50:50 with it since I originally designed this as a small group explore-and-survive romp, but I did put micro-sandbox in the writeup. The potential is obviously there given the students might plan to find a teacher as one of the objectives to help them get out of the school and survive. Just gotta let me know what you're thinking regardless.
And of course I have to decide how complicated this will make storytelling and if it's worth a try.
