Achieving 100% map completion is a common goal for Castlevania players. To do this, you must visit every single room and uncover every hidden passage. Pay close attention to your map on the top screen; any unvisited areas will appear as dark, unexplored squares. Use relics like 'High Jump' and the 'Owl' sub-weapon to reach high ledges. Remember that some areas are only accessible after acquiring specific key items or defeating certain bosses. explore the main castle thoroughly, as well as all the paintings. The 'Nest of Evil' also contributes to map completion. A fully explored map often reveals hidden rooms or items you might have missed on your first pass.
