The idea and the graphics and the sound are great!
Sometimes, picking up bullets is a little hard, as it seems you can pick up the bullet and then immediately shoot it again?
I wish there was a way to see if the bullet would kill a vampire, as sometimes it felt a bit iffy.
It also seems that your not required to solve the puzzle, you can just pick em off one by one, and retrieve it every time. Whats up with that?
