Thank you for making it. The imagery of it is striking and comes back to me every now and then. I cannot unhear "a high wall is not high to be measured in units of length, but of angle" -- beautifully put.

The idea was that it'd be good example of having to navigate somewhat foreign but internally consistent worlds, an essential text adventure skill.

Ha, I didn't realize that I was replying to the person who wrote the post!

The audience I had in mind when writing it was people who were already quite experienced in playing interactive fiction and could then be challenged in a new way while bringing their old skills to bear. So it's sort of a second-level game in that respect (so is 9:05, in different ways, as someone else mentioned).
