/************************************* * Tetris * 1. Game start interface , Display interface * 2.
Generation of squares , And determine whether there are squares in the position where the blocks are generated , Quit the game if you have one * 3. Movement of squares , rotate , Move left and right , Can it be moved * 4. Square to the end , Is the line full , Generate new squares *
