Locate the 00console.rpy file in the renpy/common folder, open it with any text editor, locate the "config.console = False" line, change it to "config.console = True", save and exit.
Start the game, load a save file, press Shift+O and the console will appear.
After that you can just input one of the above, for example if you type "shekels = 10000"(without the "") and press enter you will get 10000 funny-money.
Alternatively, you can go to
You must be registered to see the links
and simply drag and drop your save file there. You will see the same variables(plus all the rest) and you can change their values at will. After that download the modified save file and place it back in the game/saves folder.
Either way, you have now successfully escaped grinding Hell. Cheers!
