I played the first time and I kept the people alive until I just dropped dead. Figuring I did something wrong, I played it again and let the people die and still managed to fall over dead in very same spot.
Ok I know, before you guys say anything, that ImmorTall has a deep message and all, but that still doesn't make it a game. It last all of 2 minutes and from what I can tell, and letting the people die doesn't matter.
