Vampires and Garlic

The goal of Vampires and Garlic is to eliminate all vampires by throwing garlic cloves at them. After a few seconds, the garlic bulbs will explode, killing any nearby vampires. Garlic bulbs, if thrown hard enough, can also topple barrels and crates. To move heavier objects out of the way, knock the crates onto the scales and pulley systems. Throw the garlic through the cracks in the walls to reach the vampires within the buildings. How many vampires can you slay before you run out of garlic? Only by eliminating every last vampire can you proceed to the next level.
