Exactly what I was thinking, didn't have the balls to say it though haha.
Does indeed sound like a school assignment... That's why I couldn't help but laugh at the craziness of the OP lol
I did wonder if maybe it's some part of psychology project/assignment, i.e. He wants a scary house scene to test reactions of people and see what they choose to do/where they go in the house? But he doesn't know anything about programming so is asking someone else to make it for him with no clue of the time/cost of what he's actually asking for. Though tbh, I think the first suggestion is more likely
