While Castlevania II: Simon's Quest has a primary objective of collecting Dracula's body parts, there are several optional activities and items that can significantly aid Simon in his journey. These 'side quests' often involve finding hidden items, exploring optional areas, or grinding for resources.
Unlike modern RPGs, there isn't a formal quest log. Instead, these activities are discovered through exploration, cryptic NPC dialogue, or by simply knowing where to look. Engaging with these optional elements can make the main quest much more manageable, especially for new players.
