Same here. I think it is not a bug though... maybe if the piece has no pair, you have to select itself. Maybe, who knows. Not super clear.
Apart from that, it is a fine game. No other bugs, not really innovative though. Nice work for 3h!
it was a bug, I have fixed it now. The pieces have pairs. Yes, it is not much coding innovative, the main part of the game are the graphic of the pieces.
