Hi! Unfortunately, our ability to support Mac is very limited; we've had reports from certain folks that other of our Flash games aren't working for them, but it doesn't seem to happen to everyone with MacOS.
You can try the steps that Apple provides for unidentified developers, in case that's the issue: https://support.apple.com/guide/mac-help/open-a-mac-app-from-an-unidentified-dev... We don't have another solution at this time for the Mac version. We're sorry about that.
