Okay, this is a DOS game. It's a side scroller and you played the character of Dracula (I think it was Dracula, it may have been just another vampire). You could turn into a bat to fly over obstacles and you could suck blood. I also recall some vampire hunters who would throw stakes at you.
That all I can remember. Does anyone know the name of this game? And do you think it might be possible for AB to host it (I realise this is kind of a stupid question without knowing the name or the publisher, but hopefully somebody else knows

)?
