Tetris Game

• The up key is for rotation, the down key is for speeding up, and the right-left keys are for moving to the right and left.
• As you see in the gif, you can rotate, and stack the shapes, and destroy the line if it is full with the shapes.
• This game will be continued to be developed.
• Terminal dimensions should be 120x49. Otherwise, the game will not work properly.

TODO

• Fix destroying of the lines.
• Show scenes of the next shape, current score, lines, and game over.
• Show the highest score.
