Castlevania/Secrets

Bonuses
Throughout the castle, there are several special bonuses including money bags (1000 points) and crowns/treasures (2000 points). These nearly impossible to find bonuses are revealed by crouching or standing on appropriate blocks.

Pot Roasts
Life restoring Pot Roasts can be found by destroying certain blocks throughout the castle. Each Roast restores six bars of health, so finding one can easily be the difference between life and death.

Shot Multipliers
Shot Multipliers allow you to have two or three special weapons on screen at once, which lets you kill things, especially the bosses much more quickly. Multipliers can be dropped by enemies or candles, but also found in certain blocks.

Second Quest
After you beat Dracula and the game one time, you can continue after the credits roll. You will begin back at Stage 1, but the game will be much more difficult. Every time that you get hit, you will sustain four units of damage, so you can only be hit four times before dying (unless you find any Pot Roast).
