While game started, cubes will be falling automatically. Rotate and move cubes to pile up them. While a line is full, the line will be eliminated.
At last there is no idle space then game is over. Score is the number of eliminated lines.
Original speed: 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 by this value. So the falling will be quicker and quicker if it is bigger than zero.If set to zero, the falling speed will be fixed.
