Lurking Horror was my fave, but I loved leather goddesses too. A while back it was (yet one more) dream of mine to mix mapping with IF, there is a very good and inexpensive IF program called 'Adrift' which I used. The thing that always annoyed me about IF was having to think up witty comments to all the things that the player would do wrong (and there are a ton of them for each room) for the one thing he had to do right to be able to move on in the game.

The images are beautiful, crayons. I had a quick play and I don't know how you are going to solve your problems unless by, say, clicking on the stairs going north and down, the upper floor vanishes and you can see the lower floor.
