Congratulations and well done.
Here's a review that I did of 'Within The Radiant Dome' on my blog Gavin. I loved it btw. Very well done. http://swordsandstitchery.blogspot.com/2014/07/review-and-commentary-on-geoffrey.html
Thanks for the review! Glad you enjoyed it.The adventure I'm currently working on for the final round of the OSR Superstar competition has a bit of a similar vibe, though more magical and less technological. It might be up your street. It'll be PDFised at some point...
