Prompt:

I want to create a game.
To players play against each other in the same computer. One is in control of the letter L and the other controls the letter A.
We have a field divided by two with a line. Each player controls 50% of the field. The player who controls A controls the left half and the one who controls L controls the right half
At a random momemnt, the line will move towards either the left or the right.
The player who is losing ground must pres the button as fast as possible to prevent the line from moving anymore.
When that's done, the line will stay in place and players will have to wait until the line starts to move at a random moment to a random location.
The player who ends up controling 0% of the screen loses and the game ends
