I have to say... I don't play chess or roguelike games, so I am really not a good playtester for your game. It's nice to have green boxes highlighting the valid moves. The visual is interesting, bringing me back to the old black-and-white CRT era, feeling like watching The Twilight Zone TV series. I am guessing the music is supposed to be relaxing, but it feels depressing to me during the first round at least--evoking the feel of those black-and-white sad melancholy movies. I don't really have any tactics as I don't know chess, so just random moves, and watch my chess pieces disappearing one by one. :(
