Haunted Castle 3: Trevor's Quest

Haunted Castle 3: Trevor's Quest is a freeware game in the vein of Castlevania from Miguel Perez. CHC3 follows in the footsteps of other Castlevania games and offers players much of the same gameplay that they've come to expect from the side-scrolling series, complete with all sorts of various creatures from floating skulls to skeletons. Bear in mind this is a freeware game and not licensed by Konami, although some of the graphics and sound have been ripped from other Castlevania games.
