Thank you for the feedback!
The room with chairs and tables is not meant to be anything to investigate. If you don't do anything you'll get stuck in the corridor in a loop. If you watch carefully you should see a poster on a door showing a number and a book. Each book you collect will decrement the value by 1, and once all books are collected the loop will break and you can exit the school.
I'm not sure that the camera will rotate towards the right, the camera will float up and down while not moving, probably look like rotating.
I would probably make some updates hinting the player better to collect all the book. Thanks again!
