The L-Game is a simple two-player game created by Edward de Bono. Read more about it here: https://en.wikipedia.org/wiki/L_game

To play, each player gets one tetromino, and must move it first in any position, rotating if necessary. Then, they have the choice to move either of the two neutral pieces, or choose not to. The goal of the game is to make your opponent unable to move their tetromino.

Print the board, two tetrominos and two neutral pieces. Optionally, you can print the lid.
