Zombie Heads - a matching game

In Zombie Heads, you need to match up zombie heads as they are tossed into a garbage can. When two heads are matched, they explode, making room for more. The zombie heads fall at an increasing rate of speed, threatening to overflow the trash can. If they reach the top, you lose! As you destroy more and more zombie heads in a row, you unlock achievements, and increase your bonus multiplier. In a tight spot? Save the dynamite powerup to quickly clear the screen, but user beware! Using the dynamite resets your streak! Directions: - Touch one head to select it, the face will change to show you it's been selected. - Touch a matching head to explode both of them. - Touch a non-matching head to clear your selection. - The more you match in a row, the bigger the bonus. - Use the sticks of dynamite to clear the entire screen of heads at the expense of your bonus multiplier.
