Make it so the camera is glued at the top of the chessboard, and that you don’t have to click chess pieces twice (sometimes thrice or even more) to select them.
Also, when you want to take a piece, you have to click on the space they’re standing on. I think it’d be better if you could click the chess piece you want to take.
And if possible, make a daily and weekly quest for chess for more variety.
Play 3 games of chess for daily, and win 7 games of chess for weekly.
