Simon is taking another shot at this castle, but feeling horrible for the destruction he caused last time, he is now trying to respect Dracula's property and leave the place untouched (even if his intention is to kill the count).
As a minimalist variation of a pacifist goal, this movie does not contain any destruction in the levels: candles and walls are left intact, items stay untouched, and no enemy is harmed — with the exception of the bosses, who are killed mercilessly with the help of the "critical hit" glitch.
With Simon sneaking by most enemies with no subweapons and only his leather whip, this ends up being quite a stealthy run.
