I don't have access to a Mac export module (plus I'm using GM:S Standard, which is now pretty much obsolete). If any one does have one, and some time, I would appreciate it so much if you would download my source from my game page (it's a .gmx folder zipped up), and export it to Mac (link to it in the comments of my game page).
The Mac download link will say: 'Mac Download (courtesy of ____) Thanks!
