Well, I didn't quite find everything I could there, the ui graphics are prefect, the base graphics are pretty decent, but I'm not quite sure what I had to do. I only fought one vampire that killed me and I couldn't see its life?
There's something weird will colliders, it feels like to enter a cave you have to come from up and to leave it from down? At first I was lost and couldn't find a way out :(. Same for the city, I used your saved file (you uploaded the game with a save file with level 6 character :D), and I could get out of the city but I had hard time re enter.
