No checkmate, you say? Very excellent execution of the theme - seems unique too, so great idea! Does the CPU follow any logic as to when to bluff vs not? It seems to detect obvious bluffs, but not sure if you made it omniscient?
I think everything was top notch! I didn't hear any sound fx or music, so unless that was just my browser, I think that would be the main feedback I have to make the pieces feel like they are making contact with the board, and the button to have a really loud noise.
I've added this one to my favs and will be playing again. Very fun "bluff chess" idea
