In Unitale , this manifests as a battle where the enemy is not a distinct entity with a backstory, but a projection of the player’s own intent. If the player seeks violence, the mirror reflects that aggression with punishing difficulty. If the player seeks pacifism, the battle often becomes a test of patience and introspection.
