Comparing Castlevania maps can be a tricky task, as they are often large and complex. One challenge is identifying key landmarks and features to establish a starting point for comparison. To address this, try breaking the map down into smaller sections and focusing on comparing specific areas or points of interest.

Another challenge is accounting for differences in map scale and dimensions. Different Castlevania games may use different map scales, making direct comparisons difficult. To overcome this, consider using a tool or software that allows you to overlay and align maps of different scales. This will help you identify similarities and differences more accurately.
