Fun idea. The concept’s amusing, the ghost mode is cool, and the pixel art is nice.
I didn’t like how game overs tended to feel quite sudden. I think it was often that the Hunter would come through a door and there would be no way to react to him. That felt a bit troublesome. Also, a restart button after a game over would have been nice.
That being said, good work overall. If I were a Count whose mansion was turned into a hotel, I’d feel Down too.
