The first two where you meet Geoffery are fine, but the ones on the stairs block both going up and going down. I walked around the first floor for anything of importance 3 times and I couldn't find anything of note to help me get to the next floor. Maybe I am just clueless though haha
hey bro there are two staircases and one allows access tot the upper floors. u can get to this one by going through the storage room (with the knight faceplanted on the table) then turning right at the hallway and then theres a doorway to it. I will be working on making this clearer as in hindsight the first floor is pretty confusing.
