This looks great. I would have liked slightly more detail in Bernband so I'd like to try this. When I try to run it on macOS I get a system dialog saying that the application can't be opened. When I try from a terminal I get the following:
open ./BornUnderSaturn\ -\ Mac.app
The application cannot be opened for an unexpected reason, error=Error Domain=RBSRequestErrorDomain Code=5 "Launch failed." UserInfo={NSLocalizedFailureReason=Launch failed., NSUnderlyingError=0x6000002c80f0 {Error Domain=NSPOSIXErrorDomain Code=111 "Unknown error: 111" UserInfo={NSLocalizedDescription=Launchd job spawn failed}}}
I was able to fix it by running:
chmod +x BornUnderSaturn\ -\ Mac.app/Contents/MacOS/BornUnderSaturn\ -\ Mac
