The Mac version has some weird stuff going on:
- The .rpa files are all named .rap.
- The nonstandard .ttf, .otf, and .TTF font files are in renpy/common instead of in the game folder where they should be.
The result is that if somebody tries to run it with a trusted copy of Ren'Py (which I always do for malware reasons), it breaks badly. No idea if it would work when you run it by double-clicking or not.
