Here is the password to take you to Dracula.
When entering your name, leave it blank by just hitting the start button. The password doesn't seem to work unless the name is left blank. I tested multiple times and works Everytime when name is blank and never seems to work when I enter a name before password.
Blank, Blank, Blank, Holy Water
Holy Water, Holy Water, Blank, Blank
Blank, Holy Water, Blank, Blank
Blank, Heart, Axe, blank
Be sure to take advantage of the save system.
In order to damage him, you always need to hit him in the head.
1st, he'll launch projectiles at you. Hit them with the whip and they with break into more. Hit them before they hit you. While doing that, hit him in the head whenever you get the chance with whip or item.
2nd attacks, he'll spawn fire guys that will chase you until they hit you or you hit them 1st. Like before hit him in the head when you can.
3rd attacks, he'll spawn lightning attacks. They're always vertical so stand in between to avoid getting hit and hit him in the head when you have the chance.
He can be a pain in the ass so abuse the save feature. I saved after every hit on him. It takes 2-3 hits for him to lose on bar of health
