This a creative idea that piqued my interest since I am a big enjoyer of chess. I liked the concept of needing to spot cheating by player, and how sometimes the players will try to hide their cheating to make it more challenging to spot. However, the 8 bit style make it difficult to tell the difference between pieces. Also, sometimes it felt like they were playing a little too fast so you didn't have time to spot everything in time. You can restart the game which will have the exact same moves occur again, which does make it easier to spot every cheating attempt, however I'm not sure how good it is since there is no reason to play again once you found every mistake. Another thing is that finding these cheating attempts doesn't change anything on the board, I would expect it at least make the player that cheated go back or even disqualify someone after they attempted to cheat multiple times, but nothing changes when catch them cheating, which makes it feel a little pointless. Still, as a chess player I enjoyed this concept even if there was a few things I'd change.
