Castlevania: The Adventure Cheats

Much like other Castlevania games, you can keep on playing with harder difficulties after the credits roll. Once 'The End' appears on the screen, simply wait for a minute or two and the game will start you off at 'stage 05' which is really the first stage with advanced difficulty.

In the first level, do not hit the first candle. Now when you come to the 11th candle, hit it to reveal a 1-Up.
