It crashes the save, but i did use it to see the variables to input on console:
Max_Gag_res = 500
Max_PL_Orgasm = 500
Max_Pain = 500
Max_PL_Willpower = 500
futa_cum_injection = 1
My reply is honestly better since it applies to more than just ren'py games. I have used it for certain Java games for instance as well as these kinds of games.
