Shadow room is actually a reference to David Lynch's mini-series "Rabbits".

what does the teal key open tho, i cant for the life of me figure it out ;o;

Thank you everybody for your advices. I'll add map for teal key and also will write the roads to endings

Could you make a map of the place on the third lighthouse floor where the teal key is? that red light keeps getting me when I try to get the key, a map would be helpful

Explaining the general area and which door to go to doesn't ruin the experience. One thing you have to think of is the fact someone won't know where the "new areas" are if they play this after the next update or after the finished product.

The full road would include all of the spawns of the dolls and the hidden room i didn't even mention for ending E, simply saying that the end of the path will take you to the star key door on floor 3 will at least give the player direction to know if they have met all the criteria for the ending.

Telling someone where the start and destination are doesn't ruin the experience in-between, but it helps someone who may be stuck know where to go when they have everything they need, so they know if they, for example, need to find more dolls to find the ending

Well, as I said in the begining of the guide, I don't want to give the full road, cuz it will just ruin the experience of the game. Red haze is all about exploring stuff

This really isn't much of a guide, just vague hints on whats new. It would've been a lot better to actually provide details on how to get these endings other than just, "find the dolls and you'll get the ending" that much is obvious with what ending E's picture is.

What would have been a better explanation is to say that the dolls will eventually lead you to the star key door on the 3rd floor where you will enter a dark room with the dolls on both sides.

as well as you could specify that the raft you get for ending L shows up at the bunny ear room with the note, just saying Mariana doesn't really tell you where to go unless you already know.

And anyone who didnt get the Hallows Key will get it with the Save Shrine now.

I tried loading the same save file, and then I tried making a new save file and searching for them, but I will try searching the lighthouse and west hall again!

You just restarting the game and trying to load same save file, right? (if I understand you correctly)
If you have them in hall already, that means you triggered them previously. In that case you don't need to open room 104 again.
You need to start a new game, then try to go through the basement. They also appear in 1,2 floors of the lighthouse and in the west hall. If you can't find them — start new game.

I have to get the keys to room 104 but there's one of the dolls blocking the door, and they're literally no where else in the areas I've searched, and restarting the game doesn't help , so I don't know how I'm supposed to get the ending
