I went back and forth on whether to submit this to the jam or not. I originally planned to join the jam and make a chess game as my first game (ever), but since it was my first game I ended up going the safe route and remaking another game that the theme made me think of: A puzzle game for the DS called Polarium, with black and white tiles.
I ended up submitting it even though it's not chess related, since the rules seemed pretty lax, but in my defense the puzzle mode in the original Japanese game is called "Checkmate" (as is this awesome song on the soundtrack which I hope to add to the game).
