Great take on the theme! I love the monologues, and how you can just make the Demon/Teacher solve everything for you.
You could, though, make the teacher animation faster. It's quite a drag, waiting for the teacher to come in and go out.
The controls were a bit confusing, too. Why should I ask help from the demon, if I can just make them solve it? Is there any advantage?
And what was that on the page about RMB control? I never used that mechanic.
Good game, anyways!
