very interesting idea, reminds me a bit of shotgun king!
I wouldnt say Im terrible at chess but it was still pretty hard at first because I kept forgetting that pawns can go in both directions, so maybe you could make their indicator a bit bigger? then I struggled a lot with the spawn rates, for example when like 6 bishops spawn all protecting eachother so you have nowhere to go... but then at some points it almost felt too easy, because pieces only spawn on white and when there are only pawns that cant move there is no immediate danger... I even managed to create an exploit where you can force the AI to repeat the same move endlessly and not spawn any new pieces, so instead of resulting in a draw you can just cheese infinite points (see screenshot)
but overall it was very fun and I loved getting into small manageable puzzle situations! I also think I played this longer than any other game!
