Pause screen overlay shown when the player presses key 1 during gameplay. Draws two lines of text (pause message and restart prompt) over the game screen using the tile-blit helper at 44509. Sets the border to yellow (6) and waits for the player to press key 1 again. If key 1 is pressed, jumps directly to 36457 (GameEntry) to restart the game. Any other key resumes play by returning normally. If the corridor view was active (mode=1), calls 32719 to restore the room display before returning.
