not sure if it's only me but opening on mac it says the file is damaged and has to be sent to the trash
to fix open terminal and use xattr -r -d com.apple.quarantine path/to/game.app
basically macos thinks it's bad because you downloaded from the internet and adds a flag that makes the file unrunnable, by running this command you're resetting that flag, fooling macos into thinking it wasn't from the internet
