(The game teaches as you play, just start walking.)
I...feel like you must have had some very bad experiences at school, if you think what the game is doing is "teaching". I feel like I can barely control it; it's not clear to me what brings someone into my head, or what I'm supposed to do with them there (I accidentally ended up with a jumper somehow?) or, really, much of anything else. I think maybe the game needs to be a little more tutorial-like than you think.
