Im trying to run the game on macOS 10.15.4 and have also tried adding the app to have Full Disk Access in Security & Privacy but the game wont run, nothing happens. Anyone know what to do?

Apple removed 32 bit processing from macOS X Catalina (10.15.xx). The last Apple operating system that will process 32 bit programs is Mojave. Many people are furious about this issue.

Odd both the Steam and Gog store pages list the game as windows only, despite the existence of Macintosh and Linux versions. Gog has the Mac version on my game download page, but it is probably the Mac OS classic version.

Night Dive Studios should be asked about a modern version for Linux and Mac.
