Several bugs. As noted by Fes, the far right variable borks the whole thing. Also, when you click a "winning" (last/losing?) cross, it ends the game instantly, before actually drawing the cross. Because it doesn't draw the cross, you can cheat on the last one. It gave me a "win" when I started a cross that should've been blocked from the last red square by another cross. That is, there were two reds left, an unimpededed cross would've hit both, but the one I started should've been blocked from one of the reds, but it just did the "instant" win thing anyway. Well, I assume it's "win" it doesn't actually say if you win or lose, just ends the game as soon as you click. The debug area is a bit to small to read more than a few letters.
