Qwirks download

This is a a good Tetris variation with difficult computer opponents, each with unique playing style. Players can manipulate the path of falling Qwirk, rotate its position, and speed up its rate of descent. When four Qwirks of the same color connect horizontally or vertically, they explode and are eliminated, yielding points. As the player removes Qwirks from his field, he sends extra Qwirks to his opponent. Overall, a fun puzzler that's still Tetris at heart.
