I recompiled the code in the newest version of Ren'py, Version 7.0.0, and uploaded the new files. The game itself is exactly the same, but I've had some trouble running older Renpy games in the latest Mac OS and didn't want anyone having this problem with SOON. I tested the Mac build briefly and it seemed to run ok but it's possible there's issues I didn't pick up. 

Note that there used to be a single file that ran on Mac/PC/Linux, now there are two different files for Mac and PC/Linux, since that's what Ren'py does now. I've hidden the old file to prevent confusion.
