Castlevania II: Simon's Quest (Japanese title: Dracula II: Noroi no Fuuin (ドラキュラII 呪いの封印) is the story of Simon's horrible weekend without sleep. Two years after defeating Dracula, the hero is physically weakened by Dracula's curse. He must gather Dracula's remains and incinerate them at the ruins of Castlevania in order to end the curse.
Through a death warp only present in the FDS version, Fortranm and Burb defeat Dracula in record time. Please read the authors' comments for more details.
We also have a run of the NES version (which doesn't perform the death warp) right here.
