Nice idea - it definitely succeeded in making me feel a bit sick, even though I'm not currently under the influence of any substances that could make me feel that way...
BTW, it looks like the computer player goes out of its way to avoid winning - it practically forced me to win, even though I also tried to avoid it. Maybe it would be better if it were a bit more of a challenge? Letting you win from time to time would be enough for the laughs of it (famously Tic Tac Toe always ends in a draw if none of the players makes a mistake).
