Hi,
congratulations on this game.
Very nice graphics.
Unfortunately, the vampire's movements are difficult to use.
You should use the following scheme:
'W' to go forward, and 'A' and 'D' to rotate. Then you can put 'S' for back.
The direction must always be forward or backward and then there must be rotation. In this way the movement will be more natural.
You can take a look at my game "BobbyBoyUpdate" and try out how my player moves. I believe that if yours moves like mine, you will improve your playability a lot.
Good fun.
