Click to shoot fireworks at the enemies. Knight: The first enemy you see in the game. He is weak. Shielded Knight: A tougher and slower version of the original Knight that deals less damage. [BOSSES] Barbarian King: The first boss in the game. He haves a skill to increase his HP by 3. If bullet=0, click on +Bullets. Bullets cost $25.
