Gameplay will be familiar fare to most people- bounce the ball off a pad (called "shuttle" in the game) to destroy walls of crystal blocks that move towards you from the top of the screen. Certain blocks, once destroyed, yield different items that you can collect. These items can either help you, or make your job more difficult. They can reduce the size of the ball so that it is harder to steer, turn the ball into a fireball which causes bigger damage, lengthen your pad, make the ball stick to the pad (instead of bouncing off it), and many more. Certain crystals can only be destroyed with special balls, while some others require 3 hits to destroy. There are even invisible crystals that appear only after the first hit, and multiple balls to confuse you. Throughout the game's 50 levels, surprises seem never-ending, and the layout of crystal walls become increasingly devious... and challenging. Overall, Crystal Hammer is definitely one of the best Arkanoid clones ever made-- and a must-have for every action fan that will keep you addicted for hours on end. Two thumbs up, way up!
