What Kind of Game Is It?
A deck-building rogue-lite. Unlike most deck-builders, you cannot see what the enemy is about to do. You guess, you commit, and then the whole round plays out at once. One choice can decide the whole fight. Read the risk, take the reward, and win before the fight begins.
One Life Only
Permanent death. When a character dies, they are gone for good. You spent time raising that character, and one fight took them away. It is fair to ask what all that effort was for. This is the core of the game.
Seeing It From the Other Side
But there is another way to look at it. A life that cannot end is not worth much. A life that can end in one fight is worth protecting. Your characters stop being pieces in a game. They fight for the kingdom, and whether they live or die is up to you.
