Just the act of eating dots is perfectly designed, because eating them slows Pac Man down, slightly slower than the pursuing ghosts. This makes the act of eating dots a trade-off decision for the player because to eat dots – to accomplish the game’s primary goal – is to put the player in greater danger. While staying in lanes where there are no dots allows the player to move slightly faster than the ghosts, but does not accomplish the game’s goal. A lesser designed game would have not slowed down Pac Mac just the right amount when eating dots.
Насколько я знаю, (я могу ошибаться) почти ни в одной shareware-реализации Pac-Man’а подобные моменты просто не реализованы.
