Continuity mistake: When Lan is waking up first thing in the morning at the start of the game, he sits up and does not have his headband on. However, his character portrait in the dialog boxes still shows him wearing his headband, despite the fact he hasn't put it on yet.
Character mistake: On the second day when Mr. Higsby is introduced to the class, Mayl states that Higsby is "weird." However, "weird" is misspelled as "wierd".
