I like the concept, and it was executed well! I've seen one other game like this in the fam so far, but it took a more action-packed approach. I enjoyed having to read the board and guess the adversary's next move! However, sticking to the walls/corners of the board made it much easier to win (I don't know how you would solve that problem with a fixed-size board, though). Some added particles and sounds would make the action more tense. I think this game has potential post-jam!
