very cool art and game but I was also confused on what to do in the chess part. It was not letting me do the moves. I probably should/will try this again and read stuff.
Yeah, we didn't get time to do more explaining in the game, but during chess the ref will tell yoyu a price to pay, which you pay in cards, and then solve the chess puzzle. Right click to discard any cards if you need different cards for paying the cost
