Sure, but that system is incredibly clumsy and every marker is the same.
Now I had to Google where to find the final boss
Sorry game that I didn't know to go to a very specific room nowhere near the boss I just defeated.
I don't really understand what this lack of direction adds to the game. It just wastes the players time, I don't find any sense of accomplishment in accidently finding an item/room that I need to progress after randomly exploring. Other games give you a reason to back track or explore, Bloodborne for example will loop back on itself with shortcuts. This game does not do it gracefully at all.
