The goal of Claustrophobia is simple: keep the blocks from crossing the center line.To do this, fire differed colored blocks to match the colors coming at you from the top and bottom of your screen. If you hit a group of 2 or more blocks of that color, all of those blocks will be removed. But beware, these blocks don't float! So if any of the blocks on the top suddenly lose the block above them, they'll fall. And that can cause problems for the bottom rows of blocks!The larger the groups of blocks are, the higher your score gets! And if any of the falling blocks hit other groups of blocks those will be removed as well, giving you an even higher score!In addition to the normal colored blocks are special blocks. These blocks have symbols on them and can only be activated by hitting them head on with your block. Watch out though, if they fall they're gone! And not all of them are good. Try to hit them, see what they do!FEATURES:- Global score ranking- Listen to your iTunes while you play- 4 types of special blocks to switch things up- 5 different modes of play: - Classic Mode - The Claustrophobia you know and love. - Crazy Gravity Mode - Hit special gravity toggle blocks to change the direction blocks fall.
