Go to the renpy folder in the game's folder. In there, go to the common folder. Fine the 00console.rpy file within it. Open that file in your choice of text editor. Find the line that says "config.console = False" and change it to "config.console = True" - make sure that it's capitalized. The line ought to be at line 100, +- 10 lines or so.
This works for any renpy game, but it may be a bit of a chore to find the variable names. One trick is to use the command dir() which will give you all the variables in the game, and then you can check to see if there are any with obvious names - like "P_Cash" is how much money you have, for this game, or "R_Lust" is how close Rogue is to cumming. But sometimes the names aren't immediately obvious - for example, there's no "P_Lust" for how close the player is to cumming - that variable is "P_Focus".
