I have an RPG where the player fights enemies (duh). When the enemy is defeated, the player gets its gold and XP, and then the enemy is deleted. Immediately after, a new enemy is created. The new enemy has (I believe) exactly 0 health, even if I change its health variable after creating it, but it should start out with 20. I have the free version of Construct 2, if that makes a difference.
Off-topic: where are the rules? I couldn't find them.
