Silk

Silk is a fun adult Qix-style game from Subsino, a Taiwanese developer. Your goal on each level is to use the arrow keys and spacebar to "draw" lines from the edge to expose a hidden picture of a (scantily clad, of course) girl underneath. You need to expose at least 80% of the girl's picture to advance to the next level. If you get 100%, you will be treated to a neat little animation of hula dancers for a few seconds.

While drawing lines, you must avoid spiders, evil clowns, or other menacing "boss" monsters on each level that will make you lose a life when it runs into your line (or in this case, makes the guillotine blade fall a bit more toward your throat). These boss monsters grow gradually, so it is imperative for you to finish a level quickly. You can draw lines to capture food items (hamburgers, etc.) to gain time, but watch out for evil skulls - they zap your time if you run into time.
