Both of you have misguided views about the games. To DDCecil. You play as Christopher, Simon's great grandfather, not Simon.
Then to Pantechnicon. You're talking about Castlevania 2: Belmont's Revenge. You fight Soleiyu Belmont in that game, not on the original Castlevania Adventure. Other than that, Soleiyu is easy and CV2: BR is an amazing game. However, you'd probably be turned away from Stage 3 of Castlevania Adventure, a part most people have never passed.
