For the kind of game it is, the mechanics are good, if glitchy.
What it is, though, isn't spectacular, and the game itself has bad design.
(strange difficulty spikes at odd times, and unclear rules on how the vampire hunter works.)
There's alot of room to improve it, but if you do, it could be an awesome game.
As it is, it's decent enough that I was okay with wasting a little time completing it.
PS: some of the levels, vampires had directions that were unneeded, or redundant.
