I recently finished LoS2, including the DLC, and while I highly enjoyed the design of Castlevania, the castle, I didn’t really enjoy the increased Metroidvania aspect in the gameplay. The reason for that is that it didn’t really led to “wow I want to explore that later” feeling, but only “great, another ability-gate, nice that I wasted my time exploring this side path”. And there is no world map so you can mark it for later. To accommodate for that, they included an item that shows you where the closest unfound secret is. Which solves the problem by removing all the fun from it and making it literally a chore.
