May have potential, but plenty of issues.
You can keep lecturing with no stamina (you stop at 1 stamina).
Two characters seem bugged. Lyra and the bread eater. They require 120 of their subject at rank 1 affection and if you do get 120 or even 140, it still says you need 120 of that subject.
If you get the extra day, you end up with a black screen.
The daily events just repeat, so a few characters have easier affection gain and this never changes.
Cram just seems kind of worthless.
Game hit a progression block on the second month's final test. Nothing popped up and I was just left unable to move, only turn. I suspect you forgot to clean up the events so that they reactivate.
The food part just kind of got annoying after a while so I ended up just skipping it for the most part unless I needed to raise affection.
You never get int or adv quiz cards and the review modules don't seem to show up anywhere (unless they are for Cram, which seemed useless with costing 100 stamina for a single student), so no idea what those do.
Not even sure what buying books is for really or how it affects the game since the events just don't even proc.
Also, the introduction was pretty long. I feel like this would have almost been better if you had done it princess maker style with a schedule instead.
