Hey sorry for the delay, for some reason I never got alerted to this post. I'm gonna check it out real quick and get back to you.

Edit: Ok the keys are located just below the video selection buttons. I did notice there is a missing component on the board, and now it just shows "Keys" for seemingly no reason lol I will look into fixing that soon.

As far as player pieces, they work okay on my end, so it's possible that they may have been accidentally locked on yours? If that seems to be the case, try re-loading/re-opening the board. If they still seem locked, hover over the affected game piece and press the L key on your keyboard. Hopefully that helps. Let me know. :)
