Next to the central yarhnam lamp is the window that you HAVE to talk to in order to progress. How am I supposed to know that this ordinary window and lamp is required to progress? Nothing about it really stands out. Maybe experienced bloodborne players know about this window and talk to it at the start of their runs but I am not one of them.

Also please let us rebind controls for accessibility and to not mess with muscle memory (I attack with circle and roll with R2 normally)

Not criticizing this since you want it to be original to games of this era and that's what you're used to but the old school controls were frustrating and is one of the reasons I quit acclaimed games of this era so I modern control scheme would be nice. The issues I mentioned made me quit bloodborne psx

The game is FOR bloodborne veterans. So while I understand that you might not understand that's how these games function, even with that said however that's not an excuse... because it DOES stand out. It's the only ground level window with lights on... in a city of darkness where all the buildings are boarded up signs that SOMEONE is inside should have jumped out at you, there is also noise coming from this particular building/window. While the rest of your points are 100% valid and while I personally don't care about rebinding and will just work with what was given in creation (because I grew up on PS1 and that's just how it was back then), blaming the game because YOU failed to pay attention to it isn't something i'll just read and move on by. 

The game and it's dev gave CLEAR signs that it was important from the light, to the odd looking lamp hanging above it, to the noise. The fact that you missed ALL of that isn't the game or developers fault. The original version of that window was optional side content and the sound was more subtle, colors less pronounced, and it stood out even less and even then most souls players knew it stood out simply because... the light was on. I didn't comb through ALL of the windows in the game itself but I can't recall a single one being at player height and on, nor do I recall that purple lamp anywhere.

Ultimately I get it... but you can't just blame the game because you ignored the hints it gave you.
