Thirty Flights of Loving for macOS
Although Gravity Bone was released as a free game, there was never an official standalone port of it to the Mac and so as of this writing this version of the code needs the files from Thirty Flights of Loving, which also includes the other game.
The Blendo website contained a link to the source code for the Windows version but not the Mac version. After writing to Brendon Chung he supplied me with the Mac version of the source code. Both games are based off of the GPL-licensed source code for Quake II (aka "id Tech 2") and so he has no issue with releasing it here.
The Mac port of Thirty Flights of Loving was a 32-bit app and was poised to go extinct upon the release of macOS 10.15 Catalina. This repository contains the work I did to get the game running on a current Mac development environment.
Thirty Flights of Loving and its predecessor Gravity Bone were done using the KMQuake2 source port, and the Mac version was done using a port of KMQuake2 to the Mac by way of the fruitz-of-dojo port. This repository contains additional code from MaddTheSane and the YQuake2 project in order to fix some bugs introduced over the various versions of macOS.
At the time of this writing I have commented out Steam functionality as I was mostly just interested in getting it running and I don't have experience working with Steam libraries.
Have fun. For any questions I can be reached at email@example.com
