Each level in the game ends with a boss battle.
Bosses are especially fierce and deadly, with far more endurance than most other enemies.
When you encounter a boss, a health bar representing its life appears across the top of the screen. When you encounter Judgement, the purple demon will taunt you and then flutter around the giant. The giant will lumber slowly toward you, and then slash with a massive axe. When you hit the demon, the giant stops advancing and the pattern resets. After you hit the demon enough times, the giant will die.
