	Zpeligo 29 Mar 2022 07:25 There's a small chance the achievement doesn't work properly if you restart or lose a life too often due to a pointer logic that's still beyond what I know about them. It's rare but happen.

	Sryth21 4 Nov 2024 22:30 Take it slow. Let him throw fireballs and when he stops to do the fire breath, you are safe to run around and hit the hour glass. Very strange how I never fought him this way before, I usually just rush it and let him turn around.
