The game concept is very fun. I found it enjoyable to find and meet all the other students, and the dialogue system worked very well. However, I really would have liked to see more complicated exploration; I expected to be able to climb up on and explore the supersized bookshelf or desks. More sound effects also would have been nice. The background music fit well, but it fully stopped playing after a minute or two and the game fell almost completely silent.
Overall, I think it's a fun concept game that I would be interested to see further developed.
(Also, remember to set the Itch page to "click to open in fullscreen". I had to struggle a bit to move the camera more than 180 degree view, and without an awkward fix it would've been unplayable.)
