A little on the slow side...
If this game had the pace quickened a little, it would be absolutely awesome. The problem being that Vlad isn't the quickest guy in town. (I have a dead grandfather who moves quicker) and that is what really lets the games down.
The graphics are cartoony and they look pretty good. The sound gets a little annoying after a while, in the way any arcade game should, but it's not so annoying that you refuse to ever play again.
It is clear that you've thought this game through. Are you planning on a sequel (or another version of this) or are you making this just a one-off?
