In the game, it sounds like Viktor is intentionally babying you because he knows you aren't playing the real game. The questions are a bit more difficult, but it's just very relaxed. Then he tells you to puss off and get out of his school for being such a wussy. ALL the other staff members stayed away because they think "ugh, what a loser."

My theory is that lil puss mode takes place on a saturday, the teachers are just there because they still have a bit of work to do. And you're there because punishment or something? But the teachers are chill with you, because it's not even school, it's saturday! Maybe Viktor already drank a bit of vodka and that's why he's so chill. 😅
