I remember played it together OUCH! even now. I believe it's great and first model of modern quests(MMDWRDC, HoD, BB series　etc).

However...
・I needed 192b152 to play
・Massive bugs(but not gameblocking if use b152)
・Since Nightmare Lv4, becomes so hard, especially　last Lv (I can say it's not Nightmare, hell)

Now I don't know where can get b152, but I know a link of revised edition (for 192b183), if you want to play it, I tell a link.
However I don't check revised edition doesn't have gameblocking bug(s).

Oh i remember that quest but never beat it.
i dont remember why it is a really good quest

In fact, I and OUCH! enjoyed it really then, a lot of good ideas there. But now I think it's too hard as entertainment...
