This script increases the players' scores if they are alive, and moves the screen along so long as one of them is beyond the x = -1 position. If one player dies, and the other is alive, the game continues, but the dead player does not gain points anymore. If one of the players is in an "Immune" status, the game moves faster and that player gains points at twice the rate.
