Q:

Follow up : Vampiric text based adventure game

This is my 2nd attempt at this game, I took advice and tips on the last one from here.
I took tips on how to not let memory stack overflow and to write a bit better story. Do suggest on how I can improve my code in general ? Thank you.

A:

Note: those are my personal opinions, whenever I write that you should do something, treat it as 'I think you should'. Although I usually don't do that, I will not give you solutions to the 'issues' that I am going to point out, it seems like you are good at figuring things by yourself. However, if you don't know how to - ask away.
Positives

I really like the idea of the variables like answer_A.
Functions are named as I would expect them, when I read the name - I know what is happening.
Same goes for variable names, most of the variables are properly named
Your code is very readable, I didn't even have to have any explanation to understand what it is doing - keep it up!

Extract more functions

The following can be generalised to a separate function and hence you can have the same logic for other main functions.
if choice in answer_A:
        print("The garlic did stopped the vampire but it did not stopped it's blood thirsty bats.\n\n RIP")
        return "Gameover"
    elif choice in answer_B:
        print("This is not hide n'seek \n\n RIP" )
        return "Gameover"
    elif choice in answer_C:
        return "village"
    else:
        print('Invalid input')
        time.sleep(1)
        option_castle()

Printing options can be generalized as well - not only to make the code easier but so you can easily expand your number of options - read about args.
print('''    A. Take the garllic to scare the vampire.
    B. Hide
    C. Escape from backdoor.''')

Variables
"Gameover","intro", "cave" etc should be extracted to variables so you can easily translate/refactor it later.
Generalizations
You might want to extract reading user input and writing the output to a separate class/function (class is preferable). This will give you opportunity to port your game to UI other than console.
nits

Usually, it is a good practice to use  if __name__ == "__main__" (see here) when you want to run script directly (play())
Variables y and x could be better named to indicate what they contain
Extract 1 in time.sleep(1) to a variable. You might want to change it later and if you would have more functions, it would be annoying.
