Vampire Love. Castle escape

How did I get here? This castle is a terrible place even for a vampire!
I am very hungry! Where can I find fresh and tasty blood? ..
And where is my love Vampirin?
We need to find her and get out of here.
I managed to find out: I can escape from the castle by flying away.
But unfortunately I lost the ability to turn into a bat.
To regain the ability I need to create an elixir of flight.
Perhaps in this castle there are the necessary ingredients and I will be able to find the right recipe.
