Yeah, about card targeting, we had plans to put a glowing border around a card you clicked on and the same glowing border around potential targets to show where you can click on, but as always, we just ran out of time.
And about the rewards, healing the player completely was previously only a 3rd option. We had added a new gold card to the player's deck at slot one and deleted a brown card from the deck on slot two. We even had prepared UI for those, but after some thinking, we knew that we would have to show the deck structure to the player, and we didn't have time for this functionality. And after the deadline, we decided not to add those other rewards even if it was partially coded into the game, because we are unsure this could disqualify us for adding new content reasons.
