As a chess fan I was excited to play this when I saw it before ratings began. Unfortunately I did pretty often encounter a problem where I couldn't move any piece no matter where I tried. I don't know if this is somehow my fault or not but I couldn't even finish the second level because of this. Despite that I did have fun and would be willing to come back to it if I could get past the problems moving.
Edit: I did come back and finish the game but I still met the problem mentioned above once or twice.
