I like this idea, but it is missing a goal and a reason. Like a score, for example, or making this a roguelike. Of course, there is no audio. I hand-switching colours is pretty neat. I think difficulties could be a thing. Maybe in easy mode it tells you what the piece you ate was and stores all the pieces you ate, or the bot is simply easier. More player feedback; I guess most of that would be the missing audio. Does the player always start first? It is hard to know who starts, and I think it should be randomized to add more personality.
7/10, I like chess, so I might be biased.

Please make sure to send a review my way too if you have the time
