The yarnspin compiler is just the yarnspin.exe in the root of the folder. It will compile all the files in the scripts folder, create the yarnspin.dat, and run the game.
most likely, there is something missing or wrong in the script, and yarnspin.exe reports an error. If you try and run yarnspin from a commandline, you should be able to see any errors reported, and we can figure out what’s going wrong.
Also, if you want to share your script, I’m happy to help debug
