Continue game:
Begin game play and reach the "Exterminator" or "Beach Bum" level. After losing, press A + C + Start when the credits begin. Game play will continue at the last level played. Note: For later versions of the game, press Start at the credits after reaching the "Ratbreath" level.

Recharge stations:
Recharge stations appear in the following routes (in order): Right, Left, Left, Left, Right, Right, Left.

Alternate route:
During the game, you will follow directions given for turns to take, labeled like a clock (i.e. left turn is 9, right turn is 3, down is 6, and up is 12). Normally if you take a wrong turn, or a turn you were not instructed to take, you would hit a wall and explode. If you insert the game disc into an audio CD player and play track two, you can hear a phone ring followed by "Hello, Digital Pictures..." and a bizarre message repeated three times. This message played backwards is "Number Nine. Number Nine. Number Nine." If at the very beginning of the game you take three nines, or left turns, you will not explode, and the game will keep going.
