I found a typo in the early portions of the game. While punishing Debbie and bringing her up to level three, Miss Newman says "I'm impressed. I was a little sceptical at first when you had me rub her bottom."
Sceptible is misspelled, it should be "Skeptical". I don't know how this typo has survived this long, but hopefully it will be corrected now that it has been pointed out.
EDIT: I have also noticed a possible coding error. In the email you receive from Mykock about a tour of the school, the last line says "There is no rush Mr [surname], just contact me when you are ready and I shall arrange the visit.
I believe that the [surname] portion is referring to a line of code that is failing to be read properly, or the code is incorrectly written and is failing to be recognized as actual code.
EDIT: It has been shown to me by the following comment that both spellings are technically correct. Please feel free to ignore my comment about a typo, since the word skeptical/sceptible comes down to an individual preference.
