I've got a couple of tech advancement news items:

Leadlight Gamma works on macOS Catalina

On the macOS front, Apple's latest operating system is 10.15 aka Catalina. I tested that the Gargoyle-driven Mac version of Leadlight Gamma is still working on Catalina, and it is.

Text-to-speech play of LLG is now possible on Macs

Play on Macs has always been powered by the interactive fiction interpreter called Gargoyle. Gargoyle hadn't been updated updated for years until recently (late 2019) and the new version finally adds support for text-to-speech. Now, I haven't tested this yet, or figured it into the download bundles or game instructions, but it should be doable right now if you want it. There's a download of the new Gargoyle at the following link... https://eblong.com/zarf/tmp/garglk/gargoyle-2019.1-mac-nota.dmg ... which has been built to run on macOS 10.9 (Mavericks) and up. If you use that app instead of the Gargoyle(s) currently bundled with the Leadlight Gamma downloads, you should get text-to-speech capability. It will require a bit of thought, time and new docs before I make this part of the download bundles.
