Tower Toppler
Level select:
Move the Left Difficulty switch to the left during game play to
display other towers. Move the switch back to the right to select
the currently displayed tower.
Unlimited lives:
Use the "Level select" code to choose the tower immediately before
the desired tower to be played with unlimited lives. After moving
the switch back to the right, intentionally lose all lives. Move
the Left Difficulty switch to the left after the last life is lost,
but before the game over screen appears. The next tower will
appear. Move the switch back to the right to begin game play with
unlimited lives.
