Obfuscated C is always with caveats. The fact that it uses terminal escapes and stty suggests its not going to work on anything other than a colour xterm, if you're lucky, there are no sunspots and the wind is blowing in the correct direction...

I'm not sure that's a common goal for obfuscated c code

Same here. stty is available through cygwin, although I didn't result in a playable game.
