Yeah, it was a bummer of a discovery! I submitted early and when I went to record some gameplay to pull screenshots on a different Mac the build wouldn't run. Exported again as a dmg ... played fine on the machine, but not on any other Macs. I tried tracking down the Xcode and cert issue, but it was too close to the deadline by then. I'm glad at least the Windows build and the HTML version runs, even if you can't go fullscreen in browser.
Thanks for trying!
