@red-iron I agree. I'm already taking steps towards that.
@jajo I noticed that too. I'm playing with the idea of having different board types and sizes, maybe even some not chess-like boards.
@jern If played like that it might also be a good game for mobile, where you just get a push notification when it's your turn. I didn't opt-ed out of Audio, because as far as I know you aren't really punished for getting a bad score in Ludum Dare. So (because I didn't know how far others would get with their audio) I decided to stay in that category. I did opt out of Humor because it clearly isn't that type of game.
Thanks everyone for playing and giving feedback.
