Hi everyone!
My apologies that you aren't able to play the game. I am going to assume all three of you are running Catalina?
We recently went through notarization (a process Apple enforces on their latest OS for security concerns) though it seems to not be functioning and still blocking the game from being opened. We are currently looking into the issue, though it may take some time to figure out why the notarization process didn't work.
Thank you for your patience!
