This hack allows you twiddle other values to enhacne your game. Locate constant.ini in your drive letter:\jpog\data\ directory. Open the file using a text editor (like Notepad) and adjust any of the following lines to alter your game (note that the default values are listed). All of the values are self-explanatory (start drooling).
