Nice game! I think the battle system is a bit too random and could benefit from some determinism :D Like, maybe give the pieces a set of standard allowed moves (like in actual chess, lol :D) and then just occasionally use cards to go beyond that.

From the very beginning, the piece cards should have exactly the moves of the corresponding chess pieces. With a little randomness. But I made a mistake somewhere. I knew about it, but there was almost no time left. And I focused on other things. The result - now the game can be completed. So, I hope the choice was right!)
