Hello and gratulations on creating a game with an outstanding style!
Now to my observations from playing for the first 10 hours:
The Map & Navigation
The map is way too hard to navigate, this will go away after about 3-4 hours of gameplay (or faster if you are willing to sandbox and just run around and learn each room)
This is too long!
Many new players will NOT be willing to put in that time to understand basic navigation and the game can be extremely frustrating and confusing while you cannot understand the layout.
So what can be done to make the map easier to navigate for new players?
Doorways
Your doorways to new areas are already unique (stone, with light ornamentation).
Play this up even more, I would make these doorways hyper visible, have some lights on them, possibly even the name of the area they are leading into above them (organ hall, stage, circus hall, center).
Make them easy to see, even from afar and add that information.
This creates a unique landmark that can be seen across the room and helps make sense of the map much faster and on the fly.
I would also include the roman numerals on these door-names to quickly make clear which level you are on.
Rope Spots
Way too subtle, if you did not invest the time to actually go into sandbox and figure out where they are on each level these are just impossible to spot. Instead of being a broken wood stud that blends into the geometry have this again be something quite visible, even from afar. It doesn't have to be a landmark like the doorways should be, but definitely more visible than they are now.
Maybe a bigger metal hook/ring that sticks out would be better? Basically replace the studs with a unique asset that is visible at a glance and even from across the room.
