I remember there being a compass item in the bunker, which located certain notebooks at a time in the language level, but I can't seem to find it again, maybe it's because items no longer float and drop to the floor, maybe it was secluded by a few 2D barrels. The last time I found it, it was in a certain dead end corridor of the bunker, not in a room. Maybe y'all can use this compass to locate notebooks a lot easier in the language level, if you can find it and get out of the bunker fast enough before Phonty and Antibreather catch you, and hopefully Marzia isn't there near Phonty's room, because she killed me once when I returned to wind Phonty after only 2 notebooks were collected.
Also, if there was a chemistry teacher in the game, it would look similar to this:
But Viktor said, "Fuck off from my school, little pussy!" So now there will never be a chemistry teacher.
