I bet this was the show that really opened the doors for the Japanese cartoon porn market in the west. Also, I'd never seen an episode of this show, and even I vividly remember that music.
I had this game in elementary school, and it was equally frightening then. The woman who narrated the "adventure" (which included weird, fetish-inspired dress-up games) must've stood about half an inch from the microphone, and clearly had a cold/been doing nose drugs the night before.
