there's no version for Mac?
You can get it to run on Mac by installing Java with JavaFX and running the .jar file directly (perhaps other ways too). I'm not sure since I don't have a Mac to test it on, but people have been able to run it on Mac.
If installing Java with JavaFX, I recommend to go here and download JDK/JRE 19:

You must select the Full JDK or Full JRE for macOS to get the JavaFX component needed for playing videos.
That's about all the help I can give. I can't really provide support for Paradise Found on Mac. Try it at your own risk.
