Tic-Tac-Toe

good game overall, here's my suggestion:
when I change the language, it says
settings.language<key>
which I think it displays the code instead the language ?
or is it because you didn't add other languages ?
idk, but I guess it will be good to fix that
another point:
if you set the board to 3X3
and you set the winning condition to 4-in-a-row or higher
you will longer be able to win in a 3X3 board, because the conditions suggests 4-in-a-row and board is smaller than that
which yeah, the player should be smart enough to understand that and adjust well, but I guess to make the game handle such case is a good addition.
the previous point makes me also question the use for win condition <none>
because what's a game without a winning condition anyway
another point:
it will be cool to see how the computers are playing when you choose computer vs computer, instead of like getting the result immediately

overall, I guess the game is still good, it gives you the flexibility to play around with winning conditions, computer difficulties, board width and height, colors and all
