On macOS Catalina I get an error trying to open the Mac build:
> BrogueCE+HR cannot be opened because of a problem.
> Check with the developer to make sure BrogueCE+HR works with this version of macOS. You may need to reinstall the application. Be sure to install any available updates for the application and macOS.
Based on the garbage dumped in Console.app, it looks like it's trying to access a file on the disk that it isn't allowed to access without some kind of entitlement.
I assume this happens because Apple is being crappy and I'm sorry it's affecting you. :-(
You can get in touch with me on Twitter at @irskep if you want more information.
