I played this game not too long ago, it's a terrific little game. Very atmospheric but it has its flaws. I just looked at some of the screenshots from the Amiga version and was surprised to find this one:

I never found that place when I played the game as far as I can remember. Anyone else?

At church,climb rope or simply up.
I doubt amiga version was added place and scene,because of it change walkthrough.
