Thanks for your feedback! I'm taking it down for the next time I have energy to work on this enough to implement feedback.
We do have a map system that I'm able to step through (on the overarching map, I never built this for the individual rooms which I probably ought to have done.) I'm also thinking I want to do what Darius Kazemi suggests in this talk and build an option that lets players watch the map generator in action. That might be more of a stretch goal, but the basic variables are there and barring further obstacles, it'll probably happen in either an SMVM release or shortly after.
