Ooo thats a good idea! About the automatic thrashing cards for points. And can you elaborate on the 3 different buttons for cornfiming actions? I just put it as enter to confirm and select the card, unless you are talking about the mini game that goes with the attack card
The game started with Space to go through dialogue, switched to Enter to select cards, then Q to attack. All of that can be on the Spacebar or Enter. "End Turn" could also be a selectable button to remove the need for more buttons. For a turn based menu like this you really just want menu navigation, confirm, and cancel to be the only keys the user needs to press.
