Hey nukeemninja, we have some bugs to sort out from the Game Jam rush. The biggest being the one you're having where the Chess AI does not start properly on some computers. As for controls, you can click on the piece to move and then click on the space you want to move to. (We have code for the movable spaces to glow but it wasn't finished in time for the game jam build.)
We're trying to figure out the bugs and plan to update the game over this next weekend. Hopefully, check it out again after then.
And thanks again for playing!
