Hey AccordingLeaf. I personally don't have a Mac to test on in front of me, but I might have made a mistake when building for that OS. I have rebuilt and uploaded a new copy of the Mac build if you want to try downloading again. Very sorry for the inconvenience, and hope this will work better for you. If you end up not being able to play, I can reach out to support and get you a refund, or we can work together to get you a working copy of the game! Thanks for reaching out!
Thanks for troubleshooting! It still says it cannot be opened, but it definitely seems to be different from the first download. Currently there's a "Build" folder with the 151.8MB application and another "Build_BurstDebugInformation_DoNotShip" folder with a zero bytes application. Not sure if any of it makes sense. I'll try running the windows version on a different computer.
