Various Gameplay Hints
Even if you can't catch the blood from pigs in front of you, you'll want to pop them quickly so they don't chase coins off the path. Try to focus on collecting blood from pigs in the background rail. These are often easier to come by and will help you establish a quick, and early, health boost. Don't bother tapping on coins at ground / vamp level, for your vampire will collect these automatically as he runs into them.
