yeah, i think it's a tricky thing to handle with these types of games — while, like adam, i really love the concept of "show, don't tell" for stories in general, when faced with such time constraints it might be best to do a little hand-holding. perhaps relying more on the test-taking mechanic itself as opposed to pure dialogue could help? i.e. more questions to make the shift from school to psychological more gradual, or eventually introducing time, such that winning is impossible? just spitballing here.
otherwise, great game that makes aware a big problem that continues to persist today — thanks for making this!
