It was the door after 14:45 in my video. Played on Windows 10. I didn't really notice the music cutting out while playing but yeah when I watched the vid now a bit it seems really odd!
I thought the difficulty was fine, I just kept getting clipped by ranged attacks. The gameplay of the map was fine I think its just that everything looks very similar and it gets extra noticeable when there's no map.
If you don't want to rely so much on the map; one way to make it easier to find your way to different rooms can be to have some color coded lines on the floor to follow. Oh and it would be nice if locked doors were very clearly marked locked - a really bright red light tinting the ground and walls around it could work.
