In this game there will be a random shape placed in the middle of the
screen. Small tiles of different shapes will appear from the bottom of
the screen, you need to drag these tiles to fill up the shape. You can
press the spacebar to rotate the dragging piece. The larger the tile you
used, the higher the score you earned. You need to move quick otherwise
when the tiles pile up in the bottom of the screen, you lose the game.
You can discard a tile by dragging it to the hole, but scores will be
deducted.
