Run through the maze with Pac-Rat, the rodent version of Pac-Man. Your objective is to collect all of the pips strewn throughout the maze. Watch out though, because there are three hungry cats roaming through the maze as well, and they are out to get you! Try to grab the big wheels of cheese before the cats can catch up with you. This will temporarily make you invulnerable. You can even attack the cats when you're using a cheese power-up, but remember that this booster doesn't last that long! Watch the cats' movements carefully, because they are faster than your little rat!
