Demon's Crest is such a game. It is moderately well known now, but it was an unknown sensation back in 1994. It is a sequel to the Demon's Quest series, which is a sort of parallel series to Super Ghouls n Ghosts. In this game the player controls one of the bad guys (the Red Arremer) through a land more dangerous, more complicated, and more inconceivably beautiful than its predecessors.
So, just to drive the point home, it's Ghouls n Ghosts for player who wants a little bit more of the same, but awesomer.
