Sufficient blood loss! Congratulations, I committed suicide, no one will remember me! Huzzah!
Just the right level of difficulty, so it takes a couple tries to win. Or lose. Depending on how you count it. Of course the real way to do it is to lie down in a bathtub with a canister of argon gas lying on your chest and to turn on the flow valve.
I wonder if this game has a message. Perhaps that there is no victory. I was thinking of a similar possible game. The game is, it's a simulation game where you eat the right things and do the right things and your character lives to 100. And the PRIZE for WINNING? You get to be infirm, powerless, hideous, sickly and unhappy for possibly at most a few more years. Hurray!
