unfortunately the enemy chess pieces just seem to move randomly (I them once going to the same square) and not really go to get you and you cant capture them... perhaps by design but it just dont feel right when pieces I know can capture me never do.
the main problem is that you have to wait like 10 seconds (it seems) between turns and that ruins the game flow, I am glad to see you are going to continue working on it after the jam, good luck!
