Cheat mode
While playing a game game, type "gabbagabbahey" to enable cheat mode. Then, enter one of the following codes to activate the corresponding cheat function.
Note: To prevent self-destruction, re-map the bomb key to avoid conflicts with code entry. Enabling cheat mode will reset your score to 0 unless a new game is started; and may not be used during a multiplayer game. The cheat status will also be included with any games saved and may not be disabled.
