Thank you Ashley for the link and response, but I guess what I don't understand might be even more basic.
When C3 exports a linux game it comes zipped in a file with your game name. Like this: "MyGameName.zip"
Then when you extract the file you have a file named for the operating system you are using. Like this: "linux32"
Inside of that file there is an executable named: "nacl_helper_bootstrap"
I have tried to run the game with these methods so far after extracting the "linux32" file:
1. Double clicking on the "nacl_helper_bootstrap" executable. When I do this nothing happens.
2. Right clicking on the "nacl_helper_bootstrap" executable, and selecting "Execute". When I do this nothing happens.
3. Opening the file named "linux32" with the Terminal. Then typing "chmod a+x linux32" into the Terminal. When I do this I get a message saying "chmod: cannot access 'linux32': No such file or directory".
4. Opening the executable named "nacl_helper_bootstrap" with the Root Terminal. Then typing "chmod a+x nacl_helper_bootstrap" and hitting enter. Then typing "./nacl_helper_bootstrap.run" and hitting enter. When I do this I get I get a message saying "bash: ./nacl_helper_bootstrap.run: No such file or directory".
I guess I really don't understand the proper steps to run an NW.js game on linux.
