I loved the story in this CS. I mean, really did it.
Alert about spoilers
Some things you might improve to make ur custom story better:
-Decorate the corridors and some of the rooms. It feels so empty with just 1-2 doors.
-It was a little bit meh, with all the keys, sanity potion, laudanum, oil.
-It was too much oil in the beginning before you got to the room with full of keys etc. Before I got to the room I had 4(!) oil and 3(!!) with oil. Should be more greedy with the oil to make the atmosphere scarier, but I get it you didn't want to make this custom story scary.
- Some glitches that made me confused.
Things I liked with your story
-Your story-writing. A good story makes a player want to continue the custom story.
-That you had to look around carefully to progress and to get the lantern. Took a while to understand the note where it was hided

-Great mapping, but you can still improve it.
I give it 7/10
