Yay! Can't wait to play it. It has so much potential --you're a genius.
Please add local 2P (even just let player 2 control the enemies would be enough).
Being able to use long distance pieces to quickly invade the opponent's territory and win makes the game a little too easy IMO. Powerful pieces should count as LESS in the opponent's territory, because it is EASY to get them to the other side. Weak pieces like the pawns should count as more. Also, permanent death of pieces that got smashed in the last match might add more balance.
