That issue you're having is why it's called DON'T RUN.
Please use the "nw" file to play the game.
chmod +x nw, chmod +x crashpad_handler (or something like this, I don't remember the exact file name) and then ./nw
chmod +x nw
chmod +x crashpad_handler
./nw
Thank you for your help. The problem is now fixed, I just didn't know how to run the nw file. I do advise including more instructions in the readme though.
