While game started, cubes are falling automatically. Rotate and move them to pile up. While a line is full, it will be eliminated.
At last there is no idle space then game is over. Score is the number of eliminated lines.
Original Delay:The delay time (milliseconds) on every step while the cubes falling. The value be bigger, the falling be more slowly.
Accelerator:While a line is eliminated, the delay time will be minus according to this value. So the falling will be quicker and quicker.If set to zero, the falling speed will be fixed.
