What the heck, it basically runs.
Known issues:
Since it's Quixe underneath, there's no sound support.
When you save a game, you have to add the ".glksave" suffix yourself.
The "File / Open Recent..." menu is not properly updated.
The Mac binary is not signed. It may show up as "from an unidentified developer". (It should not show up as "broken". Broken is bad.)
The Windows binaries have the Electron icon (blue-green) rather than my Lectrote icon (purple, compass rose).
The Quixe version number shows as "2.1.2". It's actually a pre-release 2.1.3.
