For a long time I couldn’t get anything to spawn, until finally I accidentally pressed space and started the round. 3 pieces spawned, I had no idea what to do so I moved back to what i thought was a good place for a rook (my starting piece), one of the pieces moved diagonally - Aha a bishop! I thought - so i moved to an adjacent square where a rook would be safe from a bishop. He shot me in the face and i died instantly game over.
My point here is that you may want to think about including a tutorial or introductory phase. It seems like you’ve got some cool concept here, but it will be lost in confusion because your game lacks accessibility features / onboarding.
Great work in creating an original concept and good luck with your ideas.
