If I ran it with just

    $ chmod +x snake.com
    $ ./snake.com

... then it would try to use Mono to launch it:

    Cannot open assembly './snake.com': File does not contain a valid CIL image.

But, running it explicitly with Bash works:

    $ bash snake.com

Pretty nifty but doesn't work out of the box on any Linux, at least :p Running Debian 13.
