Really interesting concept. I think there are some design aspect that need improvement, one really nice addition would be some kind of path or animation that plays when each piece moves so you're not blindsided by the instant jumps. There are also some tricks you can do in this game that aren't allowed in regular chess. For instance, there was nothing stopping me from jumping over pieces. I could take a brook, and instantly use it to take the opponent's brook on the other side of the board. Either way it's a pretty good concept, and the enemy AI seems to be really well programmed.
