In a few words. The pieces come upside-down and in a different direction on both sides of the screen. The player has to match them by symmetry(color, shape) to form a pair which is displayed in the center of the screen. Left piece once shot is stored in the memory and displayed in the status window in the top-left corner. To complete a pair you have to shoot down its remaining part from the right side once it appears on the screen. The player has a T-minus in a form of two menaces moving from both sides; once they touch her - she dies and level is restarted. To slow their rate she has to shoot some tiles in random order. The task is to collect 5 primary pairs (and\or additional bonus 5 pairs) to complete the level.
I do not know what is the precise title of the guy who is needed - but I want a technically proficient person who can make it work neatly, maybe add some features. Well, basically, a partner, who will be interested in further cooperation and making money.
