The player score is stored using only 2 bytes at addresses 29135/6. Because of this, when the score exceeds 65535 (typically after completing all levels 4 times) it overflows and restarts counting from zero. Since the current score also works as a timer limit, this may not leave enough time for the player to complete the following level, thus loosing the game.
