I do not understand why you do this kind of Custom Story. The map design is ok, there is a new monster which is quite interesting; in other words, you have the tools to make a very good and surprising story. But there isn't any work on the storyline, it's like :
And the jumpscares, good lord ! This is absolutely not credible.
*Get an item* "WHOAW ! How unexpected ! There is a monster behind me, ready to cut off my head !"
And by the way, better to opt for a good old windscare instead of bet on the Virgin of Nuremberg who is so common and boring. I expected to collide with the penis of a naked man in the hallway, thank you god that did not happen.
To continue on the "storyline" : Even the behavior of your monster is sensless !
*Look at the avatar*
I bet that was a custom story for a guy like Pewdie or sort of. It's a pity, you have probably the skills to make a better custom story.
